1. SAFETY PRECAUTIONS

1.1 Moving Parts

Be careful not to let your fingers, hair, clothing, accessories, etc., become caught up in

the moving parts of the printer.

There are moving parts associated with the carriage motor and paper feed motor.

Carriage motor

Carriage belt, idler pulleys, and carriage

Paper feed motor

Paper feed roller, pressure rollers, spurs, pick-up roller, slow down gear, paper output

guide, and purge unit.

1.3 Ink Stains

1.3.1 Ink path

Be careful not to touch the ink path as it may stain your hands, clothes, printer, work

table etc., during servicing.

The ink path consists of the BJ cartridge nozzles, head cap, waste ink tube, head

wiper, cleaner unit, maintenance jet receiving section, and waste ink absorber.

CAUTION

Although the ink and ink optimizer for plain paper are not harmful to the

human body, they contain organic solvents indicated on the package.

Avoid getting the ink into your mouth and eyes, and store out of reach of

children.

If ink does get into your eyes, wash with plenty of water and consult a

doctor. If for some reason a large amount of ink is swallowed, consult a

doctor immediately.

Give the doctor the information on the BJ cartridge package.

This ink contains dyes, that cannot be removed from clothing, etc.

Part 1: Safety and Precautions

BJC-7100

The joints and ink outlets of the respective ink tanks of the photo BJ cartridge [BC-

62e Photo] and color BJ cartridge [BC-61] are also part of the ink path and must be

handled with care.

Unless absolutely necessary, do not remove the ink tanks from a BJ cartridge, since

air may enter the ink path and have a negative effect on print quality.

Ink Outlets

Joints

BC-62e Photo

BC-61

Figure 1-4 BC-62e Photo and BC-61

The BJC-7100 uses a variety of inks and an ink optimizer for printing on

plain paper. The ink optimizer is an almost colorless, transparent fluid.

We will refer to the ink optimizer for plain paper simply as ink optimizer or

just optimizer for simplicity purposes. We will also refer to the various

colored inks and the ink optimizer for plain paper simply as "inks".

1.3.2 Ink mist

The BJ cartridge ejects ink onto the paper. After prolonged or heavy-duty use of the

printer, a small amount of ink mist splattered during printing can dirty the printer

such as the platen.

Turn off the power, open the front cover, and clean the dirty parts with a soft moist

cloth. This is to prevent dirtying the paper, your hands, and clothing from touching

these parts.

1.4 Live Parts

When the plug of the printer's AC adapter is plugged into a live power outlet, the power

supply unit of the printer is live regardless of the power being set to ON or OFF using

the POWER button.

Be careful not to get on electric shock if you are checking the printer operation with the

covers off.

CAUTION

Do not attempt to dismantle the AC adapter. The mains AC voltage is

supplied to the primary side of the AC adapter. To prevent risk of electric

shock, do not attempt to dismantle the AC adapter to check its operation,

etc.

Figure 1-6 AC Adapter

If faulty, the AC adapter must be replaced as one unit (service part). The

structural components, including the case, are not available individually

as service parts. Do not attempt to dismantle the AC adapter.

Part 1: Safety and Precautions

BJC-7100

1.5 BJ Cartridge Metal Plate

Do not touch the BJ cartridge's metal plate as it may be very hot. The metal plate

heats up during printing and becomes particularly hot during heavy duty printing.

CAUTION

Danger! High Temperature!

Do not touch.

Metal Plate

Figure 1-7 BJ Cartridge Metal Plate

The printer has the following protective mechanisms to detect overheating:

1. Overheat detection when replacing cartridge

If overheating is detected, a beeper sounds four times and the carriage

does not return to the replacement position. This is to prevent the user

from touching the BJ cartridge's metal plate.

Resume the cartridge replacement after leaving the cartridge to cool for

several minutes.

2. Overheat detection during normal printing

The carriage movement and the paper eject operation are continued

while the printing is stopped. Depending on the outcome of the ink-out

detection after completion of printing a page, a beeper sounds to

indicate the status of the error.

Ink available: BJ cartridge overheat error (beeper sounds 7 times)

Ink out: Ink-out error (beeper sounds 3 or 4 times)

When a BJ cartridge overheat error occurs, leave the cartridge to cool

for several minutes then press the RESUME button.

These protective mechanisms are based on the temperatures detected by

the sensors in the BJ head.

If the protective mechanism is activated and normal operation cannot be

resumed after cooling the head for several minutes, see "Part 5: 6.

TROUBLESHOOTING" (page 5-13).

For details of ink-out detection, see "Part 4: 5.2.3 Ink-out detection" (page 4-48).

2. MACHINE PRECAUTIONS

2.1 BJ Cartridge Handling

2.1.1 Unpacking the BJ cartridge

Do not unpack the BJ cartridge until you are ready to use it.

Before installing the BJ cartridge in the printer, remove the cap protecting the nozzles

and gently peel off the protective tape.

Do not attempt to reuse the cap or the tape after they have been removed, as doing so

may cause faulty printing.

Figure 1-8 Removing the BJ Cartridge Cap and Tape

If you replace the cap on the color BJ cartridge or photo BJ cartridge, the

sponge in the cap may cause the colors to bleed into each other. The

nozzles may also become clogged.

Always move the carriage to the BJ cartridge replacement position before

attempting to remove or install a cartridge. Failure to do so may result in

damage to the BJ cartridge.

2.1.2 BJ cartridge protection

To prevent the nozzles from clogging, never touch or wipe the nozzles, joint pipes, or

ink tank outlets with your bare hands or with tissue paper, etc. After removing the

cap and peeling off the protective tape from a BJ cartridge, promptly install the

cartridge in the printer or store it in the cartridge holder. If the BJ cartridge is not

capped or stored in the cartridge holder, the nozzles may clog due to dried out ink or

dust, etc.

Do not attempt to leave color BJ cartridges or photo BJ cartridges with their ink tanks

removed.

BJ cartridges cannot be disassembled, reassembled, or washed.

Clogged nozzles cause faulty printing. If this problem persists even after

the nozzles are cleaned, replace the BJ cartridge.

2.1.3 Power on/off

When the printer is turned off with the POWER button, the printer automatically caps

the BJ cartridge's nozzles for protection and to prevent ink leakage.

If the AC adapter is unplugged before the printer is turned off with the POWER

button, the nozzles may not be capped. In this case, plug the AC adapter again, start

up the printer and turn off the printer with the POWER button before unplugging the

power cord. Note that, if you unplug the power during the recovery operation and

then leave the printer, the purge unit may be damaged.

If the nozzles are not capped, the ink might dry out and clog the nozzles or

leak from the cartridge.

2.1.4 When not using the printer

Keep the BC-60 BJ cartridge installed in the printer even when the printer is not in

use. The BC-62e Photo and BC-61 BJ cartridges can be left installed in the printer or

stored in the cartridge holder. This also applies when carrying, transporting, or

storing the printer.

If the BJ cartridge is taken out of the printer, dried ink or dust may clog

the nozzles, resulting in inconsistent printing.

If the printer is moved or transported with no cartridge installed, ink may

leak from the cap mechanism.

2.1.5 Ink electroconductivity

The ink used in the BJ cartridge can conduct electricity. If any ink leaks into the

printer's mechanical parts, use paper towels, etc., to wipe clean. If the ink leaks onto

the printer's electrical components, use tissue paper, etc., to wipe clean. If the ink

gets to the IC chips on the PCB, or if it is too difficult to thoroughly clean off the ink,

replace the respective parts.

Never connect the printer's power cord if ink has leaked inside the printer.

It may damage the circuitry.

2.2 Ink Tank Handling

2.2.1 Unpacking the ink tank

Do not unpack the ink tank until you are ready to use it.

Before installing it in the color BJ cartridge, remove the cap covering the ink outlets.

Figure 1-10 Removing the Ink Tank Cap

2.2.2 Preventing clogging

To prevent poor ink suction due to clogging of the joints in the BJ cartridge, never

touch the ink tank's ink outlets. After removing the cap from the ink tank, promptly

install the ink tank in the BJ cartridge to prevent the nozzles from clogging due to

dried-out ink, dust, etc. Do not remove an ink tank from a BJ cartridge unless you

are replacing it.

2.3.3 Ink leakage and dry-out

Make sure a BJ cartridge is installed before turning off the power, using the POWER

button.

When you turn off the printer using the POWER button, the printer automatically

performs the following operations:

Cleaning

Any ink left in the purge unit or in the nozzles of the BJ cartridge is removed.

Capping

To prevent ink dry-out, the BJ cartridge's nozzles are capped automatically and the

carriage is locked in position.

If you unplug the AC adapter by mistake, plug the power cord again, turn the power

on and then off again using the POWER button, then unplug the AC adapter.

If you turn the power off or unplug the AC adapter when the BJ cartridge has been

removed, the nozzles will not be automatically capped or the carriage locked in

position, and hence there is a risk of ink leaking or dry-out.

3. NOTES ON SERVICING

3.1 EEPROM Data

The printer stores the function settings and keeps track of various information

including the total sheets printed, the number of cartridge replacements, the total

waste ink amount, and the head position adjustment values. The data is stored in the

EEPROM on the logic board.

Note the following precautions during servicing:

1) Before servicing

You can check the EEPROM data with a test print. The total sheets printed can give

you an idea of how much the printer has been used.

2) During logic board replacement

Always replace the waste ink absorber when replacing the EEPROM.

If you do not replace the waste ink absorber, the data on waste ink amount will differ

from the amount of ink that can be absorbed by the waste ink absorber. There is

therefore a risk of ink leaking.

When replacing the logic board, be sure to reset all the data. Because the data on

new EEPROMs is undefined, they cannot be used until they are reset. For details of

handling EEPROMs, see "Part 3: 3.4 EEPROM" (page 3-19).

3) After waste ink absorber replacement

After replacing full waste ink absorbers, reset the EEPROM's waste ink counter.

4) If you accidentally reset the EEPROM's waste ink amount data or all data

Once reset, the EEPROM data cannot be restored. If you accidentally reset the

EEPROM, you must take the same steps as when replacing the logic board.

After the EEPROM is reset, the data it contained cannot be printed out

with a test print. If you want to check the stored data, be sure to make a

test print before resetting the EEPROM.

Note that you cannot reenter the data from the printer's control panel or

by using a computer.

If the EEPROM is faulty, or all data is reset, all data is lost. Whenever

possible, restore all data such as the head alignment to the user's

settings.

During operation, the waste ink amount (EEPROM data) is automatically

updated. An error message is displayed and operation halted when the

waste ink absorber is nearly full. If this occurs, refer to "Part 5: 6.

TROUBLESHOOTING" (page 5-13).

See "Part 3: 3.8.3 Printing EEPROM data" (page 3-23) for how to make a test

print of the stored data.

You can choose to either reset the waste ink counter or all data. See "Part

3: 3.8.2 Resetting EEPROM data" (page 3-22) for details.

3.2 Service Mode of Printer Driver

There are certain printer driver control functions, described below, that are, in

principle, hidden from the end user. These service mode functions, which must be

used with caution, are provided for service purposes only.

See "Part 3: 3.3.2 Service mode of printer driver" (page 3-18) for details.

3.3 Protecting the Power Supply

The power supply for the BJC-7100 printer consists of an AC adapter and a power supply

circuit on the logic board. Provided the AC supply is connected, the printer power supply

is live whether or not the power is set ON or OFF using the POWER button.

Always unplug the AC adapter from the power outlet before connecting it to or

disconnecting it from the printer. Ignoring this warning can result in damage and

failure of the printer power supply.

STEP 1-1

USA Only

STEP 2

STEP 1-2

Figure 1-16 Protecting the Power Supply

When moving the carriage by hand when, for example, manually capping the

ink nozzles or releasing the carriage lock, do so slowly while paying attention

to the operation of the carriage motor; the back electromotive force generated

by moving the carriage horizontally may damage the motor control board.

If it is necessary to move the carriage horizontally fairly frequently, such

as when replacing or adjusting the carriage, temporarily disconnect the

carriage motor connector from the control board.

3.5 Disassembly and Assembly

3.5.1 Parts that cannot be disassembled

Do not disassemble the ribbon cable to the head on the carriage unit. The position in

relation to the contacts with the BJ cartridge is factory adjusted, and cannot be

readjusted during printer servicing.

In addition, do not attempt to disassemble the AC adapter, BJ cartridge, or ink tanks.

In principle, do not loosen any of the screws painted red in the printer mechanism

(except when adjusting the head gap using the jig). The red screws hold the adjustable

plate that determines the gap between the nozzles of the BJ cartridge and the platen.

This gap is adjusted to the optimal value when the printer leaves the factory.

Figure 1-18 Parts that Cannot be Disassembled

In addition to the above, do not attempt to disassemble any parts not

shown disassembled in the exploded diagrams in the parts catalog.

Failure to observe this warning may result in those parts not functioning

as originally intended after they are reassembled.

3.5.2 Parts requiring careful attention during disassembly and assembly

The printer has many parts that can be damaged during disassembly and assembly.

For details, see "Part 5: 4. DISASSEMBLY AND REASSEMBLY" (page 5-4). Please read

this section carefully before attempting to disassemble and assemble the printer.

The printer also has many plastic parts. When disassembling the printer, take care

not to break or bend the plastic hooks.

Some plastic parts contain glass fibers for extra rigidity and precision, but

since their viscosity is low, the plastic hooks can break easily when

excessive force is used. Do not pull a plastic hook with excessive force

while unhooking it.

3.6 Self-Diagnosis

The printer has a self-diagnosis feature to detect hardware defects. The results of the

self-diagnosis are indicated on the LED on the control panel, and by the beeper. For

details, see "Part 3: 3.1 Error Indications" (page 3-14).

BJC-7100

1.2 Features

1. The new 600dpi BJ cartridge provides high-resolution printing at up to 1200 (H) ×

600 (V) dpi when using the exclusive printer driver.

There are three types of new BJ cartridge: BC-60, BC-62e Photo, and BC-61. (Note

that the BJ cartridge configuration differs according to the country.)

2. The printer is equipped with two BJ cartridges.

The BC-60 is normally installed in the printer and either the BC-62e Photo or BC-61

is installed as required for the type of printing to be carried out.

3. The print process uses an ink optimizer to enable maximum water resistance when

printing on plain paper (and envelopes).

In this new printing process, the surface of the paper is coated with the ink optimizer

prior to being printed. The ink optimizer is discharged from the special BJ head of

the BC-60.

4. The straight manual insertion path allows printing on a wide variety of papers.

In addition, the automatic platen-head adjustment mechanism obviates the need for

levers for selecting papers and platen-head gap.

5. The printer performs high speed print; HQ: 5.8ppm, HS: 7.6ppm (BK; PC magazine)

6. The printer is equipped with an ink-out detection function based on the conduction

of static electricity.

An electrical signal is input to the ink path in the BJ cartridge. This signal is picked

up by the electrode on the carriage, and the signal level is used to determine the

existence or absence of ink.

7. The printer is equipped with an IEEE1284-compatible bidirectional parallel interface.

This interface is compatible with nibble mode and ECP mode.

8. The built-in control mode is the Canon extended mode.

The host computer sends print signals in Canon extended mode, generated by the

special printer driver.

9. The printer is supplied with Windows 3.1, Windows 95 and Windows 98 special

printer driver.

10. The printer is powered by an AC adaptor, installed by manufucturing.

The ink optimizer printing process can be used in both monochrome and

color printing when the printer driver is set to plain paper (including

postcards and envelopes) in all but Draft mode. It cannot be used if the

driver is set to other than plain paper (special papers and film, etc.).

The ink-out detection mechanism confirms that the BJ cartridge is out of

ink. The mechanism does not measure the amount of ink remaining in

the cartridge and therefore does not necessarily indicate an error at the

point where print quality deteriorates as the ink runs out.

1.3 BJ Cartridge

1.3.1 Black BJ cartridge (BC-60)

The BC-60 BJ cartridge is used for monochrome printing and for printing using the

ink optimizer. It is a head and ink tank integrated type, disposable BJ cartridge

consisting of a unified BJ head and ink tanks for black ink and ink optimizer.

There are two parallel BJ heads, each with 304 nozzles. One head supplies ink while

the other supplies the ink optimizer.

Replace the BJ cartridge if either the black ink or ink optimizer runs out, or if

satisfactory printing cannot be achieved even after the stipulated cleaning operations

have been performed. Also replace the cartridge if more than 12 months has elapsed

after the seal is broken.

The BC-60 BJ cartridge will print approximately 870 pages of a standard 1500-

character print pattern (Default setting of Text mode).

1.3.2 Photo BJ cartridge (BC-62e Photo)

The BJ head for the BC-62e Photo has been modified to considerably improve the ink

jet emission precision.

The BC-62e Photo BJ cartridge is used for photo-realism (super photo mode) (when

printing photographs with substantial numbers of half-tones and light colors). The

cartridge consists of a main unit that separates the BJ heads, and disposable ink

tanks (BCI-62 photo).

There are two parallel BJ heads, each with 240 nozzles. One head supplies color inks

while the other supplies photo inks. Both BJ heads have three vertical rows of 80

nozzles each for yellow, magenta, and cyan.

The total 6 ink tanks for color and photo inks are integrated.

The BC-62e Photo BJ cartridge works by layering the photo inks, which are about

1/3rd the density of the color inks, thereby enabling pale colors and halftones to be

printed. The color inks are used to print denser colors and fill larger areas with one

color.

Replace the ink tanks if any of the 6 inks runs out, or if satisfactory printing cannot

be achieved even after the stipulated cleaning operations have been performed. If you

still cannot obtain satisfactory print quality, replace the BJ cartridge. Also replace the

cartridge if more than 12 months has elapsed after the seal is broken. (Replace the

ink tank 6 months after the seal is broken.)

The BC-62e Photo BJ cartridge will print approximately 90 pages per tank of a

standard photo print pattern (Reference data).

The BC-61 BJ cartridge is used for color printing (denser colors and filling larger

areas with color). The cartridge consists of a main unit that separates the BJ heads,

and disposable ink tanks (BCI-61 Color).

The BJ head has 240 nozzles supplying the color inks. There are three vertical rows

of 80 nozzles each for yellow, magenta, and cyan. The 3 ink tanks are integrated.

Replace the ink tanks if any of the 3 inks runs out, or if satisfactory printing cannot

be achieved even after the stipulated cleaning operations have been performed. If you

still cannot obtain satisfactory print quality, replace the BJ cartridge. Also replace the

cartridge if more than 12 months has elapsed after the seal is broken. (Replace the

ink tank 6 months after the seal is broken.) The BC-61 BJ cartridge will print

approximately 275 pages per tank of a standard color print pattern.

When you use the BC-62e Photo BJ cartridge to print in color using only the normal

color inks and not the photo inks, the normal color inks will run out and the ink

tanks will have to be replaced before the photo inks are used up.

The estimated print quantity for the BC-60 (approximately 870 pages in

monochrome) is for printing only in monochrome and assumes that the

ink optimizer is not used up by color printing. If the ink optimizer is used

in color printing, the cartridge may not print as many pages and it may be

necessary to replace the BC-60 even if you do not print in monochrome at all.

7) Description of input/output signals

Compatible Mode

Data Strobe [Input]

This signal is used to read DATA1 to DATA8. The signal becomes valid after the

BUSY signal goes Low and the printer outputs an ACKNLG signal. This signal is

normally High. After it goes Low, the printer receives data. When the signal

remains Low, the printer does not operate until it goes High.

Data1 to 8 [Input]

The printer receives data with the DATA STROBE signal.

The state of each bit of the signal must be maintained for at least 0.5µs from the

rising edge of the DATA STROBE signal.

Acknlg [Output]

This signal is a response signal to the DATA STROBE signal.

The host computer does not send the next DATA STROBE signal until this signal is

sent.

When the power is turned on or the BUSY signal goes Low for the input of the INIT

signal, this signal is sent regardless of the DATA STROBE signal.

Busy [Output]

When this signal is High, the printer is BUSY; when Low, the printer is READY.

The printer receives data at least 1 Byte when Data Stobe signal is input in the case

Busy signal goes to "H" regardless of receiving data.

The signal is High in the following cases:

• When receiving data

• When input buffer is full

• When INIT signal is input

• When carriage is in cartridge replacement position

• During manual cleaning

• When an error occurs (paper-out, paper jam, etc.)

• During soft power on/off sequence

• During internal initialization

PE [Output]

This signal goes High when the printer cannot feed paper. The BUSY signal goes

High and the SELECT and FAULT signals go Low.

This signal goes Low when the reset key was pressed and paper is loaded and fed.

The FAULT and SELECT signals then go from Low to High.

If paper is not ejected (paper jam) after an eject operation, this signal and the BUSY

signal go High, and the SELECT and FAULT signals go Low. In this case, the signals

do not change even if the paper is removed manually.

Select [Output]

The printer is READY when this signal is High.

This signal goes Low when an error occurs (paper-out, paper jam, etc.) or when the

carriage is in the cartridge replacement position.

Fault signal goes to low 50ms after Busy signal goes to high.

Auto Feed XT [Input]

This signal is only used for the transition from compatible mode to negotiation mode.

Part 2: Product Specifications

BJC-7100

Init [Input]

When it changes to Low, this signal sets the printer in the BUSY state, then resets

the printer by changing from Low to High.

The pules width of this signal is requiired longer than 5 micro seconds.

On completion of initialization, the head retreats to the home position and the

default print mode is selected.

Fault [Output]

This signal changes to Low when the printer detects an error and when the carriage

is in the cartridge replacement position to inform the host computer of the error

state.

Select in [Input]

This signal is only used for the transition from compatible mode to negotiation mode.

Nibble Mode

HostClk [Input]

This is the STROBE signal to read DATA 1 to DATA 8. When in negotiation phase

this is the trigger signal to send the protocol confirmation to the printer.

In nibble mode, this signal is always High so that the printer does not fetch data.

Data 1 to 8 [Input]

The data bus is not used in nibble mode.

Ptr Clk [Output]

The printer requests the host computer to read the data by making the Ptr Clk

signal Low in the reverse data transmission phase. After finishing reading, the host

computer notifies the printer of completion of data receiving by making the Host

Busy AUTO FEED XT signal High.

Ptr Busy [Output]

This signal outputs the data to be sent to the host computer in the reverse data

transmission phase. First, bit 3 of the transmission byte data is output, followed by

bit 7.

Ack Data Req [Output]

This signal outputs the data to be sent to the host computer in the reverse data

transmission phase. First, bit 2 of the transmission byte data is output, followed by

bit 6.

This signal is used as the trigger signal to inform the host computer of the printer’s

condition in the negotiation phase.

Xflag [Output]

This signal outputs the data to be sent to the host computer in the reverse data

transmission phase. First, bit 1 of the transmission data is output, followed by bit

This signal informs the host computer whether the printer supports nibble mode in

the negotiation phase.

The printer supports nibble mode when this signal level changes to Low at the same

time the Ack Data Req (PE) signal rises.

Part 2: Product Specifications

BJC-7100

Host Busy [Input]

Indicates that the host is ready to receive the data from the printer by making the

Host Busy signal Low in the reverse data transmission phase. After that, it goes

High when data is received from the printer to verify receiving data.

This signal changes to High in response to the PtrClk (ACKING) signal changing to

Low to change to the reverse data transmission phase.

Init

This signal is not used in nibble mode.

DataAvail [Output]

This signal outputs the data to be sent to the host computer in the reverse data

transmission phase. First, bit 0 of the transmission data is output, followed by bit

Informs the host computer if there is reverse transmission data or not in the

negotiation phase. If data is ready to be sent to the host computer, this signal

changes to Low.

1284 Active (Input)

This signal confirms that the printer is an IEEE 1284-compatible device. This signal

goes High at the start of the negotiation phase and remains High in nibble mode to

indicate that the printer is operating in bidirectional mode. It changes to Low in the

termination phase.

ECP mode

HostClk [Input]

This is the signal used in handshaking with PeriphAck (BUSY) signal when data is

sent from the host computer to the printer.

This signal changes to Low when data has been output to the data bus (Data1 to 8)

This signal changes to High in response to the PeriphAck (BUSY) signal rising. It

remains High in the reverse data transmission phase.

Data 1 to 8 [Input/Output]

These are input data signals when data is sent from the host computer to the

printer.

In the reverse data transmission phase, these are output signals, and the printer

outputs data to the host computer using this data bus.

Periph Clk [Output]

This signal is always High when data is sent from the host computer to the printer.

In the reverse data transmission phase, this signal changes to Low to indicate that

data is output to the host computer. This signal changes to High in response to the

HostAck (AUTO FEED XT) signal changing to High.

Periph Ack [Output]

When data is sent from the host computer to the printer, this signal changes to Low

when the printer is ready to receive data.

When the data has been received from the host computer, this signal changes to

High.

In the reverse data transmission phase, this signal indicates if the information

output from the printer to the data bus is command information or data (Low:

Command information; High: data).

Part 2: Product Specifications

BJC-7100

Ack Reverse [Output]

This signal remains High when data is sent from the host computer to the printer. It

remains Low in the reverse data transmission phase.

When switching from the forward to reverse data transmission phase, this signal

changes to Low, to indicate that a request to switch modes has been received, in

response to the fall of the Reverse Request (INIT) signal, which is sent by the host

computer to request the switch.

This signal changes to High, to indicate that the request to switch modes has been

received, when the Reverse Request (INIT) signal rises.

Xflag [Output]

This signal is always High in ECP mode.

Host Ack [Input]

When data is sent from the host computer to the printer, this signal indicates

whether the signal information on the data bus is data or command information

(Low: Command information; High: data).

In reverse data transmission, this signal is used for handshaking with the Periph

Clk (ACKNLG) signal.

When the host is ready to receive data from the printer, this signal changes to Low,

then changes to High when the data has been received.

Reverse Req [Input]

This signal changes to Low during the recovery phase (resending data) when data is

sent from the host computer to the printer.

This signal changes to High in response to the lowered Ack Reverse (PE) signal.

This signal changes to Low on transition from the idle state in the forward data

transmission phase to the reverse data transmission phase (when data is sent from

the printer to the host computer).

When Low, this signal indicates reverse data transmission.

The signal changes to High on transition from reverse data transmission to forward

data transmission.

Periph Req [Output]

This signal changes to Low when, during forward data transmission, the printer

requests reverse data transmission.

When the host computer changes from forward data transmission to reverse data

transmission, this signal changes to High at the same time as the Ack Reverse (PE)

signal in response to the fall in the Reverse Request (INIT) signal, which requests the

switch in modes by the host computer.

1284 Active (Input)

This signal goes High at the start of the negotiation phase and remains High in ECP

mode to indicate that the printer is operating in bidirectional mode. It changes to

Low in the termination phase on exiting ECP mode.

1.3.5 Cartridge container [SB-60]

The printer is supplied with a container for storing the BC-61 or BC-62e Photo BJ

cartridges for users who are using both the BC-61 and BC-62e Photo. (Note that the

BC-60 cannot be stored in the container.)

When the BC-61 is installed in the printer, the BC-62e Photo is stored in the

container, and vice versa.

The container can be mounted on the back of the printer.

When storing the BC-61 or BC-62e Photo in the container, make sure the

ink tanks are installed in the BJ cartridge holder.

Make sure that the cartridge faces the correct way in the container.

Do not shake or drop the container, as ink may spill.

The BJC-7100 use a range of inks and, when printing on plain paper, an

ink optimizer for plain paper is used. The ink optimizer is an almost

colorless, transparent fluid.

For simplicity in this manual, we refer to the ink optimizer for plain paper

simply as ink optimizer or just optimizer. We also refer to the various

colored inks and the ink optimizer for plain paper simply as "inks".

1.4 Turning Printer Power On and Off

1.4.1 Turning the power on

When the printer is connected to a power supply, press the POWER button to turn it

ON. The beeper sounds once and the printer initializes itself.

If no BJ cartridge has been installed, the POWER indicator blinks to show that the

printer is waiting for the cartridge to be installed.

If a BJ cartridge has already been installed when the power is turned on, the POWER

indicator lights to show that the printer is in standby mode.

When the printer is first turned on after leaving the factory, it automatically performs

a cleaning operation. This operation takes about 2 minutes during which the POWER

indicator blinks to show that cleaning is being performed.

1.4.2 Turning the power off

If the printer is ON, press the POWER button to turn the printer OFF.

When you turn the printer off, the printer automatically caps the BJ cartridge.

During this sequence, the POWER indicator continues to blink. The POWER indicator

turns off on completion of the power off sequence.

Before unplugging the power cable from the wall outlet, make sure that the POWER

indicator is off.

Do not unplug the power cable from the wall outlet before turning off the

printer using the POWER button.

If you unplug the power cable to disconnect the power, the BJ cartridge

capping will not be performed and ink may leak and dry on the nozzles,

deteriorating the print quality.

If you press the POWER button to turn off the power during a cleaning operation, the

POWER indicator will continue to blink until the cleaning operation has been

completed. The power turns off after the cleaning operation has been completed and

the nozzles have been capped. Note that any errors occurring after the start of the

power off sequence are ignored.

3.2 Warning Indications

The printer warns the operator of less serious error states by printing out messages

and sounding the beeper. Printing is not forcibly stopped while warnings are displayed.

BJ cartridge mismatch warning

If you select the photo ink system using the printer driver controls and start printing

with a color BJ cartridge [BC-61] installed, the printer functions as described below.

If you select the standard color ink system using the printer driver controls and start

printing with a photo BJ cartridge [BC-62e Photo] installed, it is possible to print, but

a message is displayed indicating that it would be preferable to replace the BC-62e

Photo cartridge with the BC-61 cartridge.

1) Windows 95/98

After the printer has received the print data, it displays a warning message on the

host computer’s screen. Printing does not start. Replace the BC-61 with the BC-62

Photo, then start the print operation.

2) Windows 3.1

Only the data that can be printed with the color BJ cartridge is printed. By checking

the printed page, the operator can see that there has been a BJ cartridge mismatch.

Replace the BC-61 with the BC-62e Photo, then start the print operation.

BJ cartridge overheat warning (cartridge replacement-inhibited temperature)

This warning message is displayed when you press the REPLACE button or you select

BJ cartridge or ink tank replacement via the printer driver’s controls but the head

temperature sensor has registered a temperature greater than that prescribed for the

head.

When this warning is displayed, the printer beeper sounds 4 times and cartridge

replacement is halted.

The printer resumes operating when the head temperature has dropped to the

prescribed value, or the head has been left for a minimum of 60 seconds without

further heating.

3.3 Function Settings

This printer has no function selector for setting functions. Use the Windows driver to

make the respective settings. For details, see the Windows Driver Guide included with

the printer.

3.3.1 Items set by control function

Procedure

1) Open the printer driver control dialog box.

2) Select "Custom Setting" to open the custom setting dialog box.

3) Change the parameter of the appropriate setting. (The item is ON when a check

mark appears in the checkbox.)

Settings

a) ECP mode

This setting selects whether or not to be used ECP mode when printing.

"OFF": No ECP mode (default)

"ON": ECP mode

b) High speed printing

This setting specifies whether or not to print at high speed by reducing the

response of the printer.

"OFF": Normal speed printing

"ON": High speed printing (default)

c) Pause page

This setting specifies whether or not to use the function to prevents ink transfer

between sheets by specifying a fixed waiting time after printing each page.

"OFF": No pause after printing each page (default)

"ON": Pause after printing each page

BJC-7100

3.3.2 Service mode of printer driver

There are certain printer driver control functions as service mode. These service

mode functions, which must be used with caution, are provided for service

purposes only.

Procedure

1) Open the printer driver control dialog box.

2) Select "Custom Setting" while pressing down the shift key to open the custom

setting dialog box. The dialog box contains the normal and service mode control

settings.

3) Change the parameter of the appropriate setting. (The item is ON when a check

mark appears in the checkbox.)

Settings

a) Pause scan

This setting specifies whether the carriage pauses between scans (the horizontal

travel of the carriage) during printing.

It takes ink longer to dry on transparencies and other special papers than on plain

paper, and there is therefore a risk under certain ambient conditions of a drop in

print quality. If the pause is set ON under such circumstances, the ink has a

chance to dry between scans. However, printing takes much longer.

b) Economy cleaning (skip first power-on cleaning)

This setting determines if cleaning is performed when the power is first turned on

after the power is connected.

"OFF": First power-on cleaning performed (default)

"ON": First power-on cleaning not performed

If the AC power supply is frequently disconnected (such as when the printer is

linked to a computer’s power supply), setting economy cleaning ON reduces ink

consumption and minimizes the startup time by omitting the first power-on

cleaning. When economy cleaning is set ON, the power-on cleaning using the 72-

hour timer is also omitted, and there is a serious risk of a drop in print quality if

the printer is left unused for a relatively long time.

c) Ink-out detection

This setting determines if the ink out detection function is on or off.

"ON": Ink out detection function on (default)

"OFF": Ink out detection function off

Make sure the ink out detection function is on unless dealing with a user who does

not want this function or you are checking for malfunctions in the detection system.

Part 3: Operating Instructions

BJC-7100

3.4 EEPROM

The EEPROM stores data such as the total page count, BJ cartridge

installation/removal count, total waste ink amount, and customsettings. The page

count and waste ink amount indicate the frequency with which the printer is used.

The EEPROM must be reset when the logic board, EEPROM, or waste ink absorbers are

replaced. See "Part 5: 4.3 Waste Ink Absorbers" (page 5-6) for details of replacing the waste

ink absorbers.

3.5 Cleaning the BJ Cartridge

If the printed page shows faults such as white lines or fragmentation, print a nozzle

check pattern to see if the print head nozzles are clogged. If they are, operate cleaning

function for the BJ cartridge to clear the nozzles, as described below.

In addition to cleaning the print heads using online operations via the printer driver,

the BJC-7100 also allows you to manually clean the heads using the RESUME button.

Note, however, that if you perform manual cleaning, the heads of both BJ cartridges

installed in the printer are cleaned. (You can clean just one of the heads if you use the

printer driver.)

Manual Print Head Cleaning

1) With the printer power ON, press the RESUME button until the beeper sounds

once.

2) The POWER indicator blinks. (Any paper in the printer is ejected.)

3) Both BJ cartridges installed in the printer are cleaned.

4) On completion of cleaning, the beeper sounds and the POWER indicator lights

continuously.

Deep Cleaning

If after performing normal cleaning, the print quality is still not satisfactory, perform

deep cleaning.

Deep cleaning uses more ink than normal cleaning.

1) With the printer power ON, press the RESUME button until the beeper sounds

twice.

2) The POWER indicator blinks. (Any paper in the printer is ejected.)

3) Both BJ cartridges installed in the printer are deep cleaned.

4) On completion of deep cleaning, the beeper sounds and the POWER indicator lights

continuously.

The printer also automatically performs cleaning operations at the following times:

1) The first time the power is turned on with the POWER button after the AC power is

connected when the heads are not capped;

2) When a BJ cartridge or ink tank is replaced;

3) When an ink-out error is detected (ink-out detection → cleaning → ink-out

detection → display)

4) The first time the power is turned on with the POWER button after 72 hours or

more has elapsed since the last cleaning or deep cleaning operation;

5) When the dot count exceeds the prescribed value during printing.

3.6 Test Printout

This printer has a built-in self-test function that can be executed without any

connection to a computer.

With the power off, press and hold the POWER button until the beeper has sounded

twice. Release the POWER button to start the test print.

If you print the nozzle check pattern on plain paper, you will not be able to check the

printing of the ink optimizer, which is semi-transparent.

In this case, check the checker pattern at the top right of the nozzle check pattern for

ink smears to see the general status of ink optimizer jetting.

If you need to check each nozzle for ink optimizer, print the nozzle check pattern on

transparency material for bubble jet printers. Check the reflected light from the

pattern to check the status of the nozzles. If it is difficult to see, coat the back surface

with black ink, etc., or position the transparency on black paper. If you print a nozzle

check pattern with the BC-61 cartridge installed, the part printed by the photo head

shown in Figure 3-20 will not be printed.

1.3 Print Signal Sequence

The following describes the sequence of signals from the time the host PC sends the

print signals to the printer up to the point at which printing is performed.

a) The host PC sends print signals to the printer.

The print signals consist of print data and control commands.

b) The printer controller receives the print signals and temporarily stores them in the

DRAM receive buffer.

c) The MPU fetches the print signals from the receive buffer and separates the print

data from the control commands based on the program in the control ROM.

The MPU processes the control commands based on the program in the control ROM.

d) The MPU expands the print data in the DRAM print buffer.

e) The printer controller receives the request to start printing from the MPU and the

print data is sent from the DRAM by DMA to the printer controller.

f) The printer controller converts the print data into serial data for the respective BJ

heads and outputs this data to the BJ heads with control signals.

The drive circuits in the BJ heads convert the serial data to parallel format and

control the output of inks onto the print paper as indicated by the control signals.

g) The MPU and printer controller sense the status of the BJ heads and printer and

control the printer as a whole, including the motor drivers, etc.

1.4 BJ Cartridge Drive

The BJ cartridges are driven according to the print data and control signals output by

the logic board. The control signals determine the timing with which ink is ejected from

the nozzles in the BJ heads and the amount of ink. These are optimized by the printer

controller according to the conditions shown bellow. The control signals also stabilize

the amount of ink by keeping the BJ heads at the optimum temperature.

The drive frequency is changed to 14.4kHz, 10.56kHz or 9.6kHz by print modes.

• BJ head temperature (heater board) and printer temperature

• Fluctuations in the heater characteristics of the BJ heads (head rank)

• Print mode and media being printed on

1.4.1 Print drive control

In the BJC-7100, printing is achieved by block dispersal drive, in which the three

vertical rows of nozzles fire sequentially and driven alternately odd/even to minimize

the concurrent firing of neighbouring nozzles.

The heat enable signal consists of a pre-pulse and main pulse. To keep the ink jetting

in the optimum state, the pulse width is varied according to the internal state of the

printer, such as the head rank, printer temperature, and head temperature.

The BJC-7100 uses a range of inks and, when printing on plain paper or

envelopes in other than draft mode, an ink optimizer for plain paper. The

ink optimizer is an almost colorless, transparent fluid.

For simplicity in this manual, we refer to the ink optimizer for plain paper

simply as ink optimizer or just optimizer. We also refer to the various

colored inks and the ink optimizer for plain paper simply as "inks".

2. FIRMWARE

2.1 Interface

The printer is equipped with an IEEE1284-compatible bidirectional parallel interface.

This interface supports compatible mode, nibble mode, and ECP mode.

Compatible Mode:

In compatible mode, signals are sent in one direction only, from

the host PC to the printer, as with the standard Centronics interface.

This is the default mode when the printer is turned on.

Termination:

The interface returns from nibble mode or ECP mode to compatible

mode in this phase.

Figure 4-5 Bidirectional Centronics Specifications Selection Sequence

2.1.1 Compatible mode

In compatible mode, the parallel interface sends data in 8-bit units.

Data is sent using handshaking based on the DATA STROBE, BUSY, and ACKNLG

signals.

When data (Data 1 to 8) and the DATA STROBE signal are input from the host PC, the

printer controller, which controls the parallel interface, outputs a BUSY signal and

latches the data signals as DATA STROBE falls. After the BUSY signal has been

output, the printer controller fetches the latched data via the DRAM bus to the receive

buffer in the DRAM. After writing the data to the receive buffer in the DRAM, the

printer controller outputs an ACKNLG signal, sets the BUSY signal "Low", and waits

to receive the next data from the host PC.

The BJC-7100 can reduce the response time by the operation in the printer driver.

This achieves faster printing, however, this may not work with some host computers.

2.1.2 Nibble mode

In nibble mode, 8-bit data is sent from the printer to the host PC in two 4-bit blocks.

The printer lowers the DataAvail signal when it is ready to send data to the host PC.

After confirming the fall in the HostBusy signal, the printer prepares 8 bits of data

and outputs the low 4 bits on the control signal line on the fall in the PtrClk signal.

When the PtrClk signal drops, the host PC fetches the data and raises the HostBusy

and PtrClk signals.

Next, when the printer has confirmed the second drop in the HostBusy signal, it

outputs the high 4 bits of data to the control signal line. If, after the HostBusy signal

has risen, there is no more data to be sent to the host PC, the DataAvail signal rises

and the printer enters a standby state until there is more data to be sent.

2.1.3 ECP mode

Because data is sent and received in both directions on the data bus in ECP mode,

data can be received at high speed. Because control signals can be used to separate

data from commands, and bidirectional communication can be established within this

mode, there is no need to switch to other modes when switching the direction in

which data is being sent.

The data bus switches direction from forward to reverse data transmission in

response to a fall in the AckReverse (PE) signal from the printer.

2.2 Print Modes

The printer selects the carriage operation and bubblejet drive method on the basis of

the media and print quality selected by the driver, and the print data that is received

from the host PC. This enables the printer to achieve optimum print quality, free of

smears and fragmentation.

To improve the quality of images, the printer is designed to print the data using

multiple passes of the carriage.

By increasing the number of passes for the data as a whole, the time required for the

ink for each piece of data to dry is split up, making ink smears less likely.

The printer selects the optimum print mode according to the type of BJ cartridge(s)

installed, the ink system being used, and the various settings, such as print media and

print quality, selected using the printer driver.

Part 4: Technical Reference

BJC-7100

2.2.1 Plain paper optimized printing mode (P-POP)

Only when you select plain paper (in other than draft mode) using the printer driver,

the BJC-7100 ejects ink optimizer from the BC-60's ink optimizer head.

The printer jets the ink optimizer onto the plain paper, followed by the normal ink to

minimize smearing and improve the ink's water resistance.

2.2.2 Economy print mode (Draft mode)

Economy print mode is the fastest print mode of the BJC-7100. Printing is performed

in single passes in bidirectional mode. Because of the speed and bidirectional passes,

no ink optimizer is used in this mode, which also cannot be selected when using the

photo ink system. Because less ink is used in this mode, the printed image is lighter.

2.2.3 Standard mode

The standard mode is further divided into two modes, "speed priority mode" and

"quality priority mode." The speed priority mode is suitable for printing text and

simple illustrations, whereas the quality priority mode is suitable for printing originals

that contain mainly images.

In the speed priority mode, the carriage makes a single pass per line at all times.

This mode is basically unidirectional printing. When only black is being printed, the

printing speed is improved by detecting parts of the original to be printed that do not

contain print data on each horizontal line, and printing in both directions taking

those lines as the threshold between unidirectional and bi-directional printing.

In the quality priority mode, the carriage makes three passes per line to print at

higher quality. In this mode, the printing speed decreases, and photo ink cannot be

used.

2.2.4 High quality and fine mode

Photo print mode uses the thinner inks of the Photo BJ cartridge (BC-62e Photo) to

suppress granularity when printing images with multiple halftones and high contrast.

By combining color and photo inks to achieve nine halftones, not only is the BJC-

7100 able to print high-contrast images, but also the subtle differences in

intermediate tones.

The photo inks are used in the low-density portions to minimize granularity.

600 × 1200 dpi (8pass) printing process achieves high quality printing without the

photo inks.

2.3 Smoothing Function

The BJC-7100 has two methods of smoothing black print data.

The printer driver can convert 600 × 600dpi data into data equivalent to 1200dpi (h) ×

600dpi (v). The printer itself can also convert 300 × 300dpi data into data equivalent to

600 × 600dpi.

2.4 Print Optimization Controls

2.4.1 Power monitor

When, due to high-duty printing, etc., the total head drive power exceeds the power

supply capacity, the consumption is automatically reduced.

2.4.2 Head sticking prevention

To prevent ink mist dispersion caused by high-duty printing, a one pass-worth of data

is splitted and printed as a 2 pass data.

2.4.3 Ink smear prevention

Printed pages ejected from the printer dry naturally in the paper output tray. If,

before a page has dried, the next printed page is ejected onto it, there is a risk that

the ink on the first page will be smeared.

When printing high-density images, etc., the BJC-7100 pauses the carriage between

printing scans and/or delays the ejection of the printed page, to prevent smearing.

BJC-7100

2.5 Head Overheat Protection

If the temperature of the print heads of the BJ cartridges is allowed to rise beyond a set

temperature, not only is there a risk of burns in the event that the heads are touched,

but it becomes increasingly difficult to achieve optimum print quality. The printer is

therefore equipped with an overheat protection function that uses thermal sensors in

the heads to prevent the temperature rising above the set temperature.

Print head temperature detection is effected by independent sensors in the black head,

optimizer head, color head, and photo head.

Protection level 1:

This protection level prevents the operator from touching the metal plate of a hot print

head when changing the BJ cartridge. If, when replacing a head, the head

temperature is higher than the temperature at which replacement is prevented, the

printer displays a BJ cartridge overheat warning (and the beeper sounds 4 times).

While the protection function is operating, the printer temporarily will not allow BJ

cartridge or ink tank replacement.

Protection level 2:

The carriage returns to the home position after printing each line and waits for a

maximum of 3 seconds to allow the print head to cool. This overheat protection

mechanism continues for a minimum of 20 seconds.

Protection level 3:

If the head temperature continues to rise, the printer stops printing; the carriage

continues to move and the paper is fed through the printer. The printer then discards

any further data sent from the host PC, and performs cleaning operations, ink-out

detection, and checks for failure of the head temperature sensor. If the printer

determines that the ink or ink optimizer has run out, it displays an ink-out error

when data is next received from the host PC. If the head temperature sensor is found

to be faulty, the printer displays a BJ cartridge overheat error.

If the BJ cartridge head temperature sensor is faulty, the above overheat

protection controls may not function correctly.

If it detects a fault in the head temperature sensor, the BJC-7100 printer

displays other hardware error messages (the head temperature sensor

error message may not be displayed correctly).

If the printer cannot recover from the overheat protection control

operations to normal printing, or if other hardware error messages are

displayed, replace the BJ cartridge. For details of how to recover from the

respective error states, see Part 5, Section 6, "TROUBLESHOOTING" (page 5-

13).

Part 4: Technical Reference

BJC-7100

3.1.1 Structure of printer's mechanical system

1) BJ Cartridge/Ink Tank

The printer is shipped with the BC-60 BJ cartridge, which contains black ink and

ink optimizer, and the BC-62e Photo BJ cartridge, which contains three color inks

and three photo inks. The BC-61 color BJ cartridge which contains three color inks

may be shipped instead of the BC-62e Photo.

The BC-60 has a unified print head and ink tank, while the BC-62e Photo has

separate head and ink tanks that can be replaced.

The user can decide whether to use the combination of BC-60 and BC-62e Photo or

BC-60 and BC-61 according to the type of data being printed.

2) Purge Unit

To ensure high-quality printing, the purge unit, which is driven by the paper feed

motor, caps and wipes the face of the BJ cartridge print head to make sure that the

ink can be ejected cleanly from the nozzles when printing.

Functionally, the purge unit consists of a pump and wiper.

The pump draws ink from the BJ cartridge and removes the ink from inside the cap.

The wiper wipes the face of the head. When not printing, the nozzles of the BJ

cartridge are capped to protect them.

3) Carriage

The carriage travels horizontally across the print paper driven via the carriage belt

by the carriage motor. Print signals output by the logic board are sent via the

carriage ribbon cable to the two BJ cartridges mounted on the carriage.

The wiping hook on the bottom of the carriage trips the latch lever and wiper lever so

that the ink optimizer head is wiped.

By controlling the position of the slide lock lever of the purge unit, the carriage

switches between paper feed/sheet feed drive and purge unit drive.

4) Paper Feed/Sheet Feeder

The built-in sheet feeder is driven by the paper feed motor and transports the print

paper to the paper feeder.

The paper feed, which is driven by the paper feed motor, rotates the feed rollers so

that the print paper is transported vertically.

5) Paper Output

The paper output unit prevents smearing and dirtying by ink by providing a time

interval up to when the paper being printed is stacked on top of the already printed

paper on the output tray. This unit feeds printed print paper to the output tray as

each sheet is printed.

Print paper is fed to the output tray by the power of the paper feed roller. This

power is transferred via the paper feed roller gear to the paper output roller inside

the paper output unit to rotate the paper output roller.

Paper end guides are located at both ends of the paper passage path in the paper output

unit. When the paper is being output, both ends of the print paper are lifted up to

slightly warp the paper, and the leading edge of the print paper being printed is made to

hang down so that it does not contact the already printed paper on the output tray.

6) Manual Feed Slot

Paper can be fed into the printer manually from the manual feed slot on the back.

Paper fed manually into the printer takes precedence over any print paper already in

the sheet feeder.

BJ Print Head (black head, ink optimizer head, color head, and photo head)

The heater board and aluminum plate are connected to the flexible cable.

Flexible Cable

The signal contacts are connected to the heater board by printed pattern wiring.

The contacts are in contact with the signal contacts on the carriage, and are used for

the input and output of print signals and sensor signals between the printer and BJ

print head (heater board).

Heater Board

The heater board has a built-in drive circuit, and is set against the ink room of the

head holder and the nozzles.

The electrode for the ink-out detector is located at the ink room.

The heater is aligned with the rows of nozzles against the nozzles.

Aluminum Plate

The aluminum plate supports the heater board and flexible cable.

Head Holder

The head holder supports the BJ print head.

The ink room stores the inks that are supplied to the nozzles. The ink-out detection

pulse is applied from the heater board electrode.

The nozzles are formed by aligning the ink ejection grooves with the heater array on

the heater board.

Head Stopper

The head stopper attaches the BJ print head to the head holder.

The heater board uses semiconductor technology, in which the heaters

and ICs, etc., of the drive circuit are mounted on a silicon plate.

When the heater drive starts, the ink in the nozzles gets hot, causing the

formation of many bubbles. These finally form one bubble which, as it

heats up, forces the ink to be ejected from the nozzle. Even when the

heater is stopped, the residual heat causes bubbles to continue to form

and ink to be ejected from the nozzle tips. The nozzle is replenished with

ink after the ink has been ejected.

Figure 4-19 Nozzle Arrays

In addition to the nozzles shown in Figure 4-19, all BJ print heads have

dummy nozzles at the top and bottom edges.

Also, the color head and photo head have 16 nozzles separating each

color, and designed to prevent neighboring colors mixing. The dummy

nozzles and color separation nozzles are not used for printing.

In the black head and ink optimizer head, up to 304 nozzles are used for

printing.

Nozzles 1 to 3 and 308 to 310 are for adjusting the print head alignment

(between the color head and photo head). According to the alignment

value, the 304 nozzles actually used in printing may shift up or down

within this range of 6 nozzles.

Because the black head and ink optimizer head, and the color head and

photo head, are arranged symmetrically around a center point, the nozzle

arrays are reversed.

For details of alignment, see Part 3, section 1.3.3, "Installing the BJ cartridge"

step 3) "Aligning the print heads" (page 3-5).

The heater temperature rises when turned on to pre-heat and main-heats the nozzles.

The heaters are aligned with the nozzle array against the nozzles in the head holder.

Rank resistance

Differences in the heater characteristics of the various BJ heads are ranked and

marked using their resistance, which is detected by the printer. The resistance is read

by the A/D board of the MPU as a voltage and converted to digital format to detect the

rank, allowing the BJ print heads to be controlled for optimum print quality.

Sub-heater

This heater adjusts the temperature of the heater board to stabilize the ejection of inks.

The printer drives the sub-heater according to the temperatures detected by the

head temperature sensor and printer temperature sensor, which is mounted on the

carriage board, and the print mode, etc.

Head temperature sensor

The head temperature sensor outputs the temperature of the heater board to the printer.

The voltage output by the head temperature sensor is read by the A/D board of the

MPU as a voltage and converted to digital format to detect the temperature. The

print quality is controlled and the head prevented from overheating on the basis of

the detected temperature.

*2: The ODDE and EVENE signals from the logic board are input to the black head and

ink optimizer head, and to the color head and photo head, in reverse order.

The black head and ink optimizer head, and the color head and photo head, are the

same BJ heads arranged symmetrically about a center point. The nozzle arrays are

therefore reversed.

For this reason, the order in which BLOCK1 to 6 are output, the arrangement of

IDATA, and the connections of ODDE and EVENE are reversed in order to align the

ejection of ink at the print media.

In the BC-60 and BC-61/BC-62 Photo, the odd nozzles and even nozzles correspond

because of the arrangement of the nozzles in respect to the print media. Therefore,

the ODDE and EVENE signal connections are reversed to align the ejection of ink at

the print media.

3.3 Purge Unit

3.3.1 Function of purge unit

The purge unit of the BJC-7100 printer has four caps: two for cleaning and capping,

and two for capping only.

The cap for the ink optimizer head is designed for use with the ink optimizer only so

that the ink optimizer does not get mixed with and react with the ink to block the

nozzles. Maintenance jets and wipers for the ink optimizer head only are also

provided.

1) Capping function

The capping function presses the caps of the purge unit against the face of the print

head to prevent the nozzles drying and the inks leaking.

When the cap is open and the printer is idle (waiting for data), the maintenance jets

are operated at 15 second intervals if paper is being fed. If no data is received for

120 seconds, the nozzles are capped. If no paper is being fed, the maintenance jets

are operated and the nozzles capped after a set time from the last data received. The

actual time depends on the ambient conditions and the number of times ink is

ejected, etc.

The nozzles are also capped when the POWER button is used to turn of the power.

2) Cleaning function

The cleaning function cleans the nozzles under the conditions shown below to

maintain the print quality.

In cleaning, paper fragments adhering to the face plate of the print head, ink

residue, and ink optimizer and ink aggregates, are wiped away and the nozzles are

replenished with fresh ink by purging the old ink. In addition, maintenance jets

remove any ink with higher viscosity, air bubbles, mixed inks, and other foreign

objects from inside the nozzles and prevent printing irregularities from unused

nozzles.

3.3.2 Structure of purge unit

1) Purge drive gear

The purge drive gear is driven via the transmission arm gear by the feed roller,

which is, in turn, driven by the paper feed motor. The purge drive gear operates the

cam that controls the pump operation and wiping. The cam position is sensed by

the purge sensor.

The purge drive gear switches between purging and wiping depending on its

direction of rotation.

Part 4: Technical Reference

BJC-7100

2) Wiper

After the purge operation, the rotation of the purge drive gear is switched so that,

when the cap lowers, wiping is performed. The wiper of the BJC-7100 printer's

purge unit operates in the direction of the rows of nozzles to wipe any ink from the

head face plate.

The ink removed by the wiper from the head face plate is absorbed by the cleaner

unit on the back face of the platen chassis and the cleaner on the cap unit.

In addition to vertical wiping by the purge unit, there is an additional wiper on the

left of the printer for the ink optimizer head. This special wiper operates horizontally

in relation to the rows of nozzles.

The wiper for the ink optimizer head is operated by the carriage travelling back and

forth. The effect of removing ink optimizer and ink aggregates is improved by

combining the operations of the purge unit wiper and the wiper for the ink optimizer

head.

3) Caps

The purge unit of the BJC-7100 printer has four caps: two for ink purging and

capping, and two for capping only.

After the carriage moves to the capping position, the caps are pressed against the

print head faces.

The two caps for ink absorption and capping are attached to the pump and purge

ink from the BJ cartridge in the cleaning operation.

The purged ink is sent to the ink absorber on the bottom cover unit.

After the ink has been purged, the carriage moves to the left of the capping position

to absorb any waste ink stuck in the cap. So that this waste ink does not mix in the

waste ink absorber with the ink optimizer and form aggregates, the absorber is

equipped with a wall to separate the ink and ink optimizer.

4) Pump

The pump is a tube pump in which a rotating roller is pressed against the ink tube

to create a negative pressure so that the ink is purged. The ink and ink optimizer

ink tubes are, respectively, attached to the caps.

5) Slide lock lever

The slide lock lever is linked to the transmission arm and switches the power from

the paper feed motor.

After the carriage moves further to the right of the capping position, the hook on the

back of the carriage slides the slide lock lever to the right to release the transmission

arm lock. Depending on the direction of rotation of the paper feed motor when the

transmission arm lock is released, the driving force of the transmission arm gear

drives either the purge unit or the sheet feeder.

6) Carriage lock lever

The carriage lock lever is unified with the cap unit and locks the carriage in the

capping position to prevent it from moving horizontally when the caps are pressed

against the faces of the print heads.

3.4 Carriage

3.4.1 Carriage functions

1) Attachment of print heads

The carriage mechanically attaches the BJ cartridges, which are connected to the

logic board by ribbon cables.

2) Carriage drive

The carriage moves horizontally across the print media driven by the carriage motor

via a carriage belt.

3) Paper feed motor drive switching

When the carriage moves further to the right of the capping position, it moves the

slide lock lever of the purge unit right to release the transmission arm lock and

switch the drive from the paper feed motor to the sheet feeder and purge unit.

4) BJ cartridge maintenance

In the BJC-7100 printer, the ink optimizer head wiper is operated according to the

position of the carriage.

When the carriage moves left, the side of the ink optimizer head presses against the

wiper lever on the left of the printer to set the wiper. When the carriage then moves

right, the hook on the bottom of the carriage pulls the latch lever so that the ink

optimizer head wiper wipes the face of the ink optimizer head.

3.4.2 Carriage structure

1) Print head mount

The cartridge hook secures the BJ cartridge to the carriage with a plate spring.

When the BJ cartridge is locked on the carriage, the signal contacts of the ribbon

cable are pressed against those of the bubblejet head so that the print signals are

transferred from the logic board to the BJ cartridge.

2) Carriage drive mechanism

The stepping-type carriage motor moves the carriage horizontally across the print

media, the drive being transmitted by the carriage belt. The home position sensor

(photo-interrupter) on the carriage board detects the home position edge of the

chassis as the initial position, then the stepping pulse is applied to the carriage

motor to control the carriage. The carriage motor is current-controlled by the motor

drive control from the carriage motor driver. The excitation signals that drive the

carriage motor are controlled to the optimum drive pulse width by the printer

controller. Mechanical print aberrations during bidirectional printing are

automatically corrected by software adjustment of the timing based on home

position edge detection.

3) Paper feed motor drive switching mechanism

The paper feed motor drive switching mechanism switches the paper feed motor

drive to the purge unit, paper feed, or sheet feeder according to the position of the

carriage.

Except when the carriage is at the right edge of the printer, the slide lock lever of the

purge unit locks the operation of the transmission arm.

When the carriage is moved further to the right of the capping position (the right

edge of the printer), the slide lock lever is released. While the lock is released, the

direction of paper feed motor rotation is switched to select either purge operation or

sheet feeder operation. If the feed roller is rotated in the direction of feed while the

slide lock lever is released, the transmission arm gear moves to the sheet feeder

drive gear to drive the sheet feeder.

If the feed roller rotates against the direction of feed while the slide lock lever is

released, the transmission arm gear moves to the purge drive gear to drive the purge

unit.

4) Ink optimizer head wiper drive mechanism

The ink optimizer head wiper wipes the rows of ink-optimizer nozzles horizontally

when a page is printed using the ink optimizer (when printing on plain paper in

other than draft mode). The movement of the carriage operates the latch lever and

wiper lever.

By combining the ink optimizer head wiper with the purge unit wiper, it is possible

to improve the removal of the hard-to-eliminate ink optimizer and ink aggregates in

one wiping operation.

3.5 Paper Feed/Sheet Feeder Mechanism

3.5.1 Paper feed/sheet feeder mechanism functions

1) Paper feed function

The paper feed mechanism has two paths: the path taken by sheets fed

automatically from the sheet feeder mechanism and sheets fed manually through

the manual feed slot. The built-in sheet feeder is driven by the paper feed motor,

and loads and automatically feeds the print media. Even envelopes are

automatically fed without the need to operate mechanical paper select levers, etc.

When pages are fed manually, the manually fed page takes precedence over any

media loaded in the sheet feeder.

When the print paper is detected by the paper end sensor (photointerrupter), it is

automatically fed to the top-of-page position on the platen by the paper feed roller.

During printing, the page feed is controlled by controlling the rotation of the paper

feed roller.

On completion of printing, the page is ejected by the paper output roller.

2) Auto platen-head gap adjustment function

The BJC-7100 printer can print without switching the carriage position according to

the thickness of the media being printed on.

The paper feed roller is pressed up by coil springs toward the pressure roller while

the paper output roller is also pressed up by coil springs toward the spurs. The gap

between the head face and the printed media is therefore kept constant regardless of

the thickness of the print media.

3.5.2 Paper feed/sheet feeder mechanism structure

The sheet feeder of the BJC-7100 printer has no mechanical paper selection lever.

Provided the print media is within the specifications, the media is fed without having

to adjust the carriage position, etc., for the paper thickness.

The print media is loaded into the sheet feeder with the two points of the leading edge

and the left corner picked up by the pickup corners and pickup hooks. When the

drive from the paper feed motor is transferred to the sheet feeder gear, the pickup

roller turns and the printer starts printing.

Print media such as plain paper are fed while pressed against the pickup corners and

pickup hooks and fed into the paper feed mechanism. When feeding stiffer materials

such as envelopes, the rigidity of the paper is sufficient that the pickup hooks and

pickup corners are pressed down and the material can be fed.

The initial position of the pickup roller is determined by the pickup roller sensor

(photointerrupter) on the logic board sensing the flag.

When the print media is detected by the paper end sensor, it is automatically fed to

the top-of-page position. If no print media is detected even after a feed operation, a

paper-out or paper-jam error message is displayed. When manually feeding paper,

the user manually inserts the print media via the manual feed slot until it reaches the

paper end sensor.

Because manually fed print media are fed through a different path than media

automatically fed from the sheet feeder, print media can be manually fed even when

media are loaded in the sheet feeder.

Print media that has been fed to the paper feed mechanism are fed to the top-of-page

position when the paper end sensor has sensed their existence for two or more

seconds.

4. PRINTER ELECTRICAL SYSTEM

4.1 Overview of Printer Electrical System

The printer's electrical system can functionally be split into the logic (logic board and

carriage board) and the power supply.

The logic converts the data received from the interface into print signals and printer

command signals, and drives the BJ cartridge and motors while monitoring the various

sensors.

The power supply distributes the DC input power from the AC adaptor into power

supplies to drive the logic board, motors, and print heads, etc.

When the AC adaptor is connected to a power outlet and a DC supply is therefore input

to the BJC-7100 printer (and the printer has not yet been turned on using the POWER

button), all buttons except the POWER button are inactive, the photointerrupter

sensors are inactive, and any signals input from the interface are ignored. In all other

respects, the hardware is active.

4.2.2 Logic components

1) MPU (IC1)

The MPU accommodates a 32-bit CPU, 25-bit address bus, 2KB work RAM, and nine

peripheral IO ports (interrupt controller, DMAC, timers, IO ports, AD converter,

DRAM controller, chip select controller, monitor timer, clock & power manager).

Internal CPU

The 32-bit CPU has 16 32-bit general-purpose registers and operates in sync with a

20MHz external clock input.

Address bus

The 25-bit address bus port is connected to the printer controller.

Data bus

The 16-bit data bus port for external devices is connected to the 8Mbit control ROM

and printer controller.

Internal RAM

The MPU has 2KB of internal RAM with 32-bit access.

Interrupt controller

The MPU has 21 interrupt request factors and 5 external interrupt factors, each

triggering interrupt processing.

Direct memory access (DMA) controller

The MPU has a 4-channel DMA controller that supports a 64MB address space.

Timer (stepping motor controller/sense signal controller)/monitor timer

The timer has two realtime port timer channels and seven multifunction timer

channels, which are connected to the respective sensors and motor drivers.

The stepping motor controller outputs double 1-2 phase excitation drive signals for

the carriage motor and 2-phase excitation drive signals for the paper feed motor.

The monitor timer monitors the signals at the realtime port timer terminals.

Part 4: Technical Reference

BJC-7100

DRAM controller

The DRAM controller controls the 10-bit addressing, reading/writing, RAS/CAS, and

refresh of the 8Mbit DRAMs (4Mbit ×2).

Chip select controller

The chip select controller shows that a valid address has been output for the set

area. The chip select controller is connected to the CARTRIDGE button, RESUME

button, POWER button, and printer controller.

Clock & power manager

The clock and power manager controls the transition to low power-consumption

mode. The WAKE UP pin is connected to the reset IC, and inputs the request to

wake up from low power-consumption mode.

2) Printer controller (IC2)

The printer controller includes the CPU interface, DRAM interface, Centronics interface

controller, print head controller, data processing controller, and IO ports, etc.

CPU interface

The CPU interface controls the writing to and reading from the CPU in sync with a

20MHz external clock input.

DRAM interface

The DRAM interface controls the 10-bit address and 16-bit data bus, the reading

and writing, RAS/CAS, and refresh of the 8Mbit DRAM through the DRAM bus,

which is independent of the MPU bus.

Centronics interface controller

The Centronics interface controller uses handshaking using the BUSY and ACKNLG

signals to receive the 8-bit parallel data sent in sync with the data strobe (STROBE)

signal from the host PC. It also controls the other interface signals. The data

received from the interfaces is stored in the DRAM receive buffer. The MPU analysis

this data and, if deemed to be print data, it is processed by the DMA.

When the printer initialize (INIT) signal is input from the interface, the Centronics

interface controller outputs a BUSY signal. When INT0 is output to the MPU, the

printer is initialized after any print data in the print buffer has been printed.

Print head controller

To drive the print head, the print head controller outputs the block signal and heat

enable signal at the same time as the print data read from the DRAM print buffer is

sent as serial data to the print head.

The transfer of print data (IDATA OM, IDATA BK, IDATA PH, IDATA CL) to the print

head is synchronized to the 5MHz clock HDCLK signal. The block signals (BE0,

BE1, BE2, ODDE, and EVENE), the pulse signals (HEAT OM, HEAT BK, HEAT PH,

and HEAT CL), and the head temperature signals (SHON OM, SHON BK, SHON, PH,

and SHON CL) are output to drive the print head.

Data processing controller

The data processing controller processes the data in the print buffer by DMA.

The data processing controller performs palette expand processing of the print data

for photo printing, 1200dpi smoothing, and conversion of the raster print data into

column oriented print data

Part 4: Technical Reference

BJC-7100

IO ports

The BJ cartridge rank signals, etc., are input to the IO ports. The power indicator

and error indicator lighting control signals, etc., are output from the output ports.

3) Control ROM (IC3)

The 8Mbit control ROM contains the printer control program.

4) DRAMs (IC5 and IC6)

The 8Mbit DRAMs (4Mbit ×2), which are controlled by the printer controller, are

used as the receive buffer, download buffer, print buffer, and working area.

5) Reset IC (IC8)

The reset IC senses the supply voltage when the power is turned on or when it is

interrupted, and resets the MPU and printer controller.

6) EEPROM (IC7)

The 2Kbit EEPROM, which is controlled by the printer controller, stores the various

printer settings, total waste ink amount, page count, print head removal/

installation count, and resume count, etc.

7) Paper feed motor driver (IC14)

The paper feed motor driver, which is controlled by the MPU, performs constant

current bipolar drive of the paper feed motor, which is controlled using 2-phase

excitation. There are two drive circuits in the IC.

8) Carriage motor driver (IC13)

The carriage motor driver, which is controlled by the MPU, performs constant

current bipolar drive of the carriage motor, which is controlled using double 1-2-

phase excitation.

The carriage motor switches the peak current among 5 steps according to the

switching signals from the MPU to maintain optimum carriage motor drive. There is

one drive circuit in the IC.

Part 4: Technical Reference

BJC-7100

Purge sensor

The purge sensor uses a transmission-type photointerrupter to detect the capping

position of the purge unit. When the flag on the cam gear in the purge unit interrupts

the purge sensor, the module phase is deemed to be in the capping position.

Paper end sensor

The paper end sensor uses a transmission-type photointerrupter to detect the presence

of paper in the paper feed system. When the paper presses against the paper end

sensor arm, the paper end sensor is interrupted, indicating that paper has been picked

up by the paper feed system.

Pickup roller sensor

The pickup roller sensor uses a transmission-type photointerrupter to detect the initial

position of the pickup roller of the sheet feeder. When the flag in the pickup roller

interrupts the pickup roller sensor, the pickup roller is deemed to be in the initial

position.

Home position sensor

The home position sensor uses a transmission-type photointerrupter to detect the

home position of the carriage. When the home position edge of the chassis interrupts

the home position sensor on the carriage board, the carriage is deemed to be in the

home position.

Printer temperature sensor

The thermistor on the carriage board detects the temperature inside the printer.

The printer fetches the voltage output by the printer temperature sensor. This voltage,

which varies according to the temperature, is converted from analog to digital to

determine the printer temperature. The temperatures detected by the printer

temperature sensor and the head temperature sensor are used to control the printer to

achieve optimum printing, and to prevent overheating.

The head temperature sensors are built into the heater boards of the

respective print heads. See Part 4, section 3.2.2, "Structure of BJ head unit"

(page 4-19) for details.

The printer decides if an error has occurred from the readings from the

various sensors. For details, see Part 3, section 3.1.2, "Service calls" (page 3-

15).

The states of the purge sensor, paper end sensor, pickup roller sensor,

and home position sensor are detected by the MPU's input ports. The

detection signal is inverted according to whether the sensor is interrupted

or open.

5.2 Miscellaneous Detection Functions

In addition to sensor-based detection functions, the BJC-7100 printer also has the

following detection functions.

5.2.1 Waste-ink amount detection

This function processes the amount of waste ink (and ink optimizer) in the waste ink

absorbers.

The printer stores the total waste ink amount absorbed by the waste ink absorbers

from cleaning and maintenance jet operations in the EEPROM on the logic board.

Post-absorption evaporation is taken into account when calculating the amount. The

total waste ink amount is updated when the power is turned off, on completion of

cleaning operations, and when a page is output. When the waste ink amount

approaches the absorber's capacity, the printer stops printing.

When the waste ink amount (or ink optimizer amount) reaches 95% of the

waste ink absorber capacity, the printer generates a waste ink alarm (operator

call). You can press the RESUME button to continue operating the printer.

When the waste ink amount (or ink optimizer amount) subsequently

reaches 100% absorber capacity, the printer outputs a waste-ink full error

(service call) to prevent ink leaks.

5.2.2 BJ cartridge detection

The detection signals from the index unit in the print head heater board are used to

detect the presence and type of BJ cartridge.

For details, see Part 4, section 3.2.6, "BJ cartridge detection" (page 4-28).

5.2.3 Ink-out detection

1) Detection operation

An ink-out detection pulse is output to the ink paths in the ink room in the head

holder. The pulse is transmitted via the ink path to the ink sponges and received by

the electrode on the carriage. It is then amplified by the carriage board and read by

the AD board of the MPU, and converted from analog to digital to detect the

existence of ink.

The electrode is located opposite the ink room in the head holder.

2) Timing processing

Ink-out detection is performed for all inks in a single sweep in the following order:

ink optimizer, black ink, color ink, and photo ink.

In the case of the color and photo inks, detection proceeds from yellow through

magenta to cyan. Post ink-out detection processing differs according to the timing.

Part 4: Technical Reference

BJC-7100

3) Ink-out error display

When an ink-out error occurs, replace either the BJ cartridge or ink tanks by either

pressing the REPLACE button on the printer or using the printer driver utility.

The cartridge or tank replacement procedure is as follows:

1) If the black ink or ink optimizer has run out, the ERROR indicator turns ON and

the beeper sounds 3 times. If the color or photo inks have run out, the beeper

sounds 4 times.

If you press the RESUME button, the beeper sounds again so that you can know

which ink has run out.

2) Press the REPLACE button to move the carriage to the cartridge replacement

position so that you can replace the appropriate BJ cartridge or ink tank.

If there is any print data in the receive buffer, the printer restarts printing.

An ink-out error message is displayed on the utility sheet of the printer driver to

indicate the ink that has run out.

Follow the instructions displayed on the host PC's screen to replace the BJ cartridge

or ink tank.

When using the bidirectional interface, the head alignment mode is automatically

selected after the BJ cartridge has been replaced. Follow the instructions on the PC

screen to align the print heads.

Ink-out detection is designed to inform the operator that the ink has run

out. This function does not automatically halt printing before the ink

actually runs out or before print faults develop due to bubbles in the ink

paths.

After replacing a BJ cartridge, be sure to align the BJ cartridges.

If you deal with the ink-out error at the printer rather than using the

printer driver, or if you use the printer driver utility, but the interface in

use is not bidirectional, head alignment mode is not automatically

selected. It is therefore necessary to manually select head alignment mode

and align the heads. See Part 3, section 1.3.3, "Installing the BJ cartridge"

(page 3-4) for details of head alignment.

Note that the ink-out detection can be disabled using the printer driver's

hidden functions.

See Part 3, section 3.3.2 "Service mode of printer driver" (page 3-18) for details

of the printer driver's service mode.

4. DISASSEMBLY AND REASSEMBLY

4.1 Disassembly and Reassembly

When disassembling or reassembling the printer, refer to the parts catalog.

The Figure No. of the illustrations in the parts catalog are in the order of the

disassembly sequence.

The parts catalog also contains close-up diagrams where additional care is required.

4.2 Notes on Disassembly and Reassembly

Note the following when disassembling or reassembling the printer.

4.2.1 Main cover

Before removing or installing the main cover, remove the connector cover. It is

extremely difficult to remove or reinstall the main cover, and parts can easily be

broken, when the connector cover is attached to it.

Figure 5-2 Main Cover and Connector Cover

4.2.2 Carriage unit

When the cartridges are installed and the power is OFF, the carriage is normally

locked in the capping position. The locking mechanism is in the purge unit and

prevents the carriage moving from the capping position exposing and potentially

damaging the print head while the printer is being shipped or moved.

When servicing the printer, you can manually release this lock using the following

procedure.

4.3 Waste Ink Absorbers

If you are replacing the waste ink absorber (and/or waste ink optimizer absorber)

because of a waste ink alarm or waste-ink full error, replace both top and bottom

absorbers together. Also replace the absorbers for the maintenance jets. In other

cases, replace both top and bottom absorbers if possible even when there is

comparatively little waste ink. For various manufacturing reasons, several different

materials are used for the waste ink absorbers. If you replace only one of the

absorbers, the top and bottom may be of different materials, which could result in

problems. (All service parts absorbers are of the same material. Differences in

materials are visually apparent.)

Clean the absorber cover if necessary.

Be sure to reset the EEPROM when you replace the waste ink absorbers. If you do not

reset the EEPROM, the waste ink alarm or waste ink full error will not be cancelled.

See "Part 3: 3.8.2 Resetting EEPROM data" (page 3-22) for details of how to reset the

EEPROM.

5. ADJUSTMENTS

5.1 Adjustment Locations

5.1.1 Adjusting registration

Adjust the registration along the horizontal and vertical directions using the printer

driver. This adjustment is the same as the operation when the user installs the

printer or replaces the BJ cartridge. For details, see "Part 3: 1.3.3 3) Aligning the print

heads" (page 3-5).

5.1.2 Checking and adjusting the head gap

Check that the head gap is correct when you have loosened the following screws, for

example during replacement of parts, or when the printer has been strongly impacted

for example by its being dropped.

This check is also necessary if the paper scrapes against the head during printing or

when color drifts frequently.

The head gap must be adjusted if it has deviated out of the allowable range of 1.2 to

1.6 mm.
