Setting Up the Printer

1-5

Choosing a Place for the Printer

Note: If you plan to use a printer stand, make sure it meets the

following requirements:

The stand must support at least 30 lb or 14 kg (twice the

weight of the printer).

The stand must not tilt the printer more than 15 degrees from

horizontal. With a cut sheet feeder, the stand must keep the

printer level.

If the paper supply is below the printer stand, make sure that

the paper cannot catch on the underside of the stand or on

the stand supports.

Make sure that the power cord and the interface cable do not

interfere with paper feeding. If possible, secure them to a

printer stand support.

WARNING:

Avoid locations that are subject to direct sunlight,

excessive heat, moisture, or dust.

Avoid using electrical outlets that are controlled by

wall switches or automatic timers. Accidental

disruption of power can wipe out information both in

your computer’s memory and in your printer’s

memory.

Avoid using outlets on the same circuit with large

motors or other appliances that might disturb the

power supply.

Keep the entire computer system away from potential

sources of interference such as loudspeakers or the

base units of cordless telephones.

Setting Up the Printer

Printer Selection Menus

Most application programs let you specify the type of printer you

are using so that the program can take full advantage of the

printer’s features. Many of these programs provide an installation or

setup section that presents a list of printers to choose from.

Choosing from a menu

Because the family of Epson printers shares a great many commands,

you can use an application program even if it does not list your

printer on its printer selection menu. Choose from the following list

(the printers are listed in the order of preference):

L-1000

L-750

LQ-850/950/1050

LQ-500

LQ-2550

LQ-800/1000

LQ-1500

If none of these printers is listed, select the first one available on the

following list.

Epson printer

Standard printer

Draft printer

To use all the features of your printer, however, it is best to use a

program with one of the LQ printers on its menu. If your program

does not list these printers, contact the manufacturer to see if an

update is available.

Paper Handling

2-6

Using Single Sheets

Reloading during printing

When you print a document more than one page long using single

sheets of paper, there are two ways your software can allow you to

load a new sheet at the end of a printed page:

If your software sends characters in a continuous stream, the

printer stops printing when it reaches the bottom of the paper.

When this happens, the page ejects and the ON LINE light goes

off automatically.

If your software handles printing page by page, it probably

stops sending characters at the end of a page and prompts you

to insert more paper. In this case, the ON LINE light may remain

on. If it does, the first thing you should do is press the ON LINE

button once to take the printer off line.

In either case, once the ON LINE light is off, remove the sheet that

has just been printed and load a new sheet as before. Press ON LINE

to start printing the next page.

Paper Handling 2-7

Using Continuous Paper

To print on continuous paper, you need to install the pull tractor

unit. With the pull tractor installed, you can print on continuous

paper with a width of 4 inches (101 mm) to 10 inches (254 mm).

If the pull tractor is already installed, skip to “Positioning your

continuous paper supply” later in this chapter.

DIP Switches

Auto line feed

When auto line feed is on (DIP switch 2-4 on), each carriage return

code (CR) is automatically accompanied by the line feed code (LF).

Input buffer capacity

The input buffer stores data from your computer. If you want to

free your computer for other tasks while the printer prints, change

the setting to 8 Kbytes (DIP switch 2-5 on). Before defining user-

defined characters, however, be sure to set the switch to 1 Kbyte

(off).

Print direction for graphics

The printer ordinarily prints text bidirectionally for speed and prints

graphics characters unidirectionally for precise vertical alignment.

You can, however, change text printing to unidirectional with the

software command ESC U1. If DIP switch 2-6 is on, you can

change graphics character printing to bidirectional with ESC U0. If

DIP switch 2-6 is off, graphics character printing is unidirectional

whether or not ESC U0 is used.

Page length

DIP switch 2-1 lets you select a page length of 11 inches (27.94 cm)

or 12 inches (30.48 cm). If you are using paper that is 12 inches

long, you can set this switch on. For 11-inch paper the factory

setting is off.

Using the Printer

3-9

DIP Switches

Skip over perforation

DIP switch 2-3 controls the skip over perforation function. If this

switch is on when you are using continuous paper, the printer

leaves a one-inch (25.4 mm) margin between the last printed line on

one page and the first printable line on the next page so that the

printer skips over the perforation.

Most application programs take care of the top and bottom

margins. Therefore, do not turn on skip over perforation unless

your program does not provide these margins.

If you adjust your top of form position to the proper point, you

can get half of the margin at the bottom of one page and half at the

top of the next page as shown below.

Using the Printer

Selecting Typestyles

Your printer can produce a wide range of typestyles by using

different character fonts, pitches, widths, and other enhancements.

You can select the character font using a software command, the

SelecType feature on your control panel, or by setting DIP

switches.

Built-in character fonts

Your printer has three built-in character fonts:

Using the Printer

Selecting Typestyles

Draft mode uses fewer dots per character for high-speed printing,

which makes it ideal for rough drafts and editing work.

Roman and Sans Serif are Letter Quality (LQ) fonts. Letter Quality

takes a little longer to print, but produces fully-formed characters

for presentation-quality documents.

Optional font modules are also available for use with your printer.

For more information, see the section on the Multi-Font Module in

the Appendix.

Selecting a font with SelecType

To select a font using SelecType, follow these steps:

1. Be sure the printer is on, contains paper, and is on line.

2. Check to see that the printer is not receiving data (the READY

light should not be flickering).

3. Press the FORM FEED button until the two SelecType lights match

the desired font, as shown below.

Using the Printer

Selecting Typestyles

SelecType skips over the SLOT option (both lights on) if an optional

font module is not installed.

The font selected by SelecType remains valid until another font is

selected by a software command or until the printer is turned off,

reset, or initialized.

Selecting a font with DIP switches

You can set your favorite font as the default font by setting DIP

switches 1-4 and 1-5.

The printer comes with Roman as the default font. If you wish to

change it, set the DIP switches as shown in the table below.

CAUTION: Be sure the printer is turned off before

changing any DIP switch settings.

Problems and Solutions

This chapter discusses problems you may encounter and their likely

solutions.

This section lists possible problems and likely solutions. For

additional information, see “Where to Get Help” on the inside front

cover of this guide.

The printer does not print

Be sure that the printer is turned on and the POWER light is on.

If the printer is turned on but the POWER light is not on, check

to see that the printer is fully plugged in and that the electrical

outlet is also turned on.

Be sure that the ON LINE light is on. If it is not on, press the ON

LINE button.

Be sure that the printer is connected to the computer. Check

both ends of the cable between the printer and the computer.

Be sure that the printer is not out of paper. (The PAPER OUT

light should be off.)

If the printer still does not print, disconnect the printer from the

computer and try the self test described in Chapter 1. If the self test

works properly, the printer is working, and the problem probably

lies in the computer, the software, or the cable. If the self test does

not work, contact the store where you purchased your printer or

call the Epson toll-free number.

4-2

Troubleshooting and Maintenance

Problems and Solutions

The printout is spaced incorrectly

Text is printed all on one line, or the printer is inserting extra blank

lines between lines of text.

If all the text is printed on the same line, no line feed signal is

being sent at the end of each line of text. Turn DIP switch 2-4

on.

If the printer is inserting extra blank lines between lines of text,

extra line feed signals are being sent. Turn DIP switch 2-4 off.

If the printer inserts extra blank lines even after turning DIP

switch 2-4 off, you may need a different cable which disables

the AUTO FEED XT signal of your interface.

The printout is faint or uneven

The ribbon may not be properly installed. See the section on

ribbon installation in Chapter 1.

The ribbon may be worn out. See the section on replacing the

ribbon later in this chapter.

The paper thickness lever may be in the wrong position. See the

section on the paper thickness lever in Chapter 2.

The print head may be worn out. This is especially likely if

parts of printed characters are missing. Contact an Authorized

Epson Dealer to have the head replaced. Never attempt to

replace the head yourself because other parts of the printer

should be checked at the same time.

Troubleshooting and Maintenance 4-3

Problems and Solutions

The printer stops printing

The printer may be out of paper. Check the paper supply.

The paper may be jammed. Remove the jammed paper and

reload.

The ribbon may be jammed. See the section on replacing the

ribbon later in this chapter.

If the READY light is off and the ON LINE light is flickering, the

printer has stopped to allow the print head to cool. Printing

resumes soon; you do not have to do anything to restart it.

If the printer stops, the beeper sounds, and the ON LINE light

does not flicker, turn the printer off and then turn it back on

and try to print again. If the printer beeps again and does not

print, take it to a qualified service person.

Single sheets do not feed properly

The position of the paper release lever may be wrong. Push it

back to the single-sheet position.

The paper may be too large or too small. See the printer’s paper

specifications in Chapter 5.

The paper guide may not be installed properly. See the section

on installing the paper guide in Chapter 2.

The cut sheet feeder mode may be selected by the DIP switch.

See the section on setting DIP switches in Chapter 3.

4-4

Troubleshooting and Maintenance

Problems and Solutions

Continuous paper does not feed properly

The position of the paper release lever may be wrong. Pull it

forward to the continuous paper position.

The paper may not be mounted on the sprockets correctly. See

that the sprocket holes of the paper fit correctly over the

sprockets.

The paper guide may not be installed properly. See the section

on continuous paper in Chapter 2.

The paper supply may be stacked too far from the printer or

not aligned with the tractor. Also, there may be some obstacle

in the way of the paper or something on top of the paper

supply. See Chapter 2 for instructions on the proper placement

of the paper supply.

The printout is not what you expect

The wrong international character set may be selected. See the

section on international character sets in Chapter 3.

The wrong character table (italics or Epson Extended Graphics)

may be selected. See the section on character tables in Chapter 3.

The font, pitch, or size may not be selected properly. See that

your software is correctly set up for your printer.

Your application program may be changing the SelecType

settings. Use the program’s setup (or installation) procedure to

remove the codes that interfere with your SelecType settings.

Another solution is to use the printer control codes for your

application program instead of SelecType to control your

printing. The manual for your program can tell you how to

change the printing style.

Troubleshooting and Maintenance

4-5

Cleaning the Printer

To keep your printer operating at its best, you should clean it

thoroughly several times a year.

Follow these steps to clean the printer.

1. Be sure the printer is turned off.

2. Remove the paper guide, tractor unit, and any installed options.

3. Use a soft brush to carefully clear away all dust and dirt.

2. “Return” denotes the twisted-pair return, to be connected at

signal ground level. For the interface wiring, be sure to use a

twisted-pair cable for each signal and to complete the

connection on the return side.

3. All interface conditions are based on TTL level. Both the rise

and the fall times of each signal must be less than 0.2

microseconds.

4. Data transfer must be carried out by observing the ACKNLG

or BUSY signal. (Data transfer to this printer can be carried

out only after receipt of the ACKNLG signal or when the

level of the BUSY signal is LOW.)

Interface Specifications

Printing enabled/disabled signals and control conditions

The table below shows the relationship between printing being

enabled or disabled, the on line/off line status, and the receipt of

the data on/off control characters, DC1 or DC3.

While printing is disabled, character data is being received and acknowledged

so that the printer can look for another DC1 character, which would allow it to

resume printing.

5-10

Technical Specifications

Initialization

There are three ways that the printer can be initialized (returned to

a fixed set of conditions).

1. The power is turned on.

Hardware initialization

2. The printer receives an INIT signal at the parallel

interface (pin 31 goes LOW).

3. Software sends the ESC @ (Initialize the printer)

Software initialization

command.

These three kinds of initialization have slightly different effects. In

particular, ESC @ resets the font to the current SelecType setting;

the other two methods reset the typestyle according to the default

settings selected by the DIP switches within the font compartment.

Also, ESC @ does not initialize the printer mechanism, clear the

input data buffer, or clear the user-defined character set.

Removing the upper case

WARNING: High voltages are present inside the printer

when the power is on. Do not attempt to remove the

upper case unless the printer is turned off and the power

cord is unplugged.

Also, try not to touch contacts on the circuit board of the

printer because many of the components can be destroyed

by the static electricity present in your body.

1. Unplug the power cable from the electrical outlet.

2. Remove the font compartment cover.

Appendix A-3

The Interface Boards

CAUTION: Use caution when removing or attaching the

upper case to avoid damaging the printer.

3. To remove the upper case, first put the printer on a table or

desk so that its front extends slightly over the edge, allowing

access to the openings on the front of the underside of the

printer.

WARNING: Be sure that the printer is not so far forward

that it is in danger of falling off the table.

The Interface Boards

Note: Two screws are labelled CG. Be sure to remove the one

indicated in the illustration below.

Installing the board

There are two basic types of interface board designs-the frame

ground (FG) wire is attached for one type and not attached for the

other. This difference does not affect the operation of the interface

in any way.

1. If the interface board comes with an FG (frame ground) wire

that is not already attached to the board, attach the wire as

shown below on the left.

FG wire attached

FG wire not attached

Appendix A-7

The Interface Boards

Carefully place the interface board next to the printer as shown

below. Use the CG screw to connect the round end of the FG

(frame ground) wire to the main board.

3. Holding the interface board level, rotate it clockwise into

position and attach it to the main board. Be sure that the

connector pins are properly inserted into the mating connector.

Appendix

A-8

The interface Boards

Secure the board with the three screws provided.

5. For all interface boards except the #8143 new serial interface

board, set the DIP switches on the interface board according to

the manual accompanying your interface board. (If you have the

#8143 board, see page A-12.)

6. Reattach the upper case as described in the following section.

Appendix A-9

The Interface Boards

Attaching the upper case

1. Fit the hinges of the upper case into the openings in the lower

case. Now partially lower the upper case.

WARNING: Take care not to pinch the FG wire between

the upper and lower cases.

2. Carefully insert the control panel cable into the connector

labelled CN4 on the main board.

A-10

Appendix

The Interface Boards

Close the upper case. Press down on the front of the case to

lock it into place.

4. Reattach the font compartment cover.

WARNING: When you use the optional interface, be sure

to disconnect the printer cable from the printer’s built-in

parallel interface. You should never leave two interface

cables connected at the same time.

5. Replace the ribbon cartridge, printer cover, and any other

necessary parts or options.

A-11

Appendix

The Interface Boards

#8143 new serial interface board

If you are using an optional interface, you may need to match the

communications protocol of the printer and the computer so they

can communicate properly. Use the information in your optional

interface manual or your computer’s manual to match the computer

with the interface.

For the #8143 optional interface board, use the DIP switch settings

shown below. These DIP switches are on the interface board, not

on the printer.

The Multi-Font Module

The optional Multi-Font Module ( #7407) gives you seven additional

fonts for your printer. Once you install it in the slot, the following

fonts are available:

Courier, Prestige, Script, OCR-A, OCR-B, Orator, and Orator-S.

The Multi-Font Module is installed in the slot in the printer. See the

manual that comes with the module for full information on using

the Multi-Font Module.

Note: Font modules #7400, #7401, #7402, and #7403 can also

be used with your printer.

The following samples show the character set available for each

font.

condensed

Printing in which each character is approximately 60% of the width

of standard characters. Useful for fitting wide tables or spreadsheets

onto the paper.

GL-1

Glossary

continuous paper

Paper which has sprocket-feed holes on each side, is perforated

between pages, and is supplied in a folded stack. Also called fanfold

paper.

control code

Besides the codes for printable characters, the ASCII standard also

includes 33 other codes which are called control codes. These

control codes perform such functions as sounding the beeper and

performing a carriage return or line feed.

The black roller that provides a backing for the printing.

print quality

Your printer has two types of print quality: draft and Letter

Quality. Draft is for high-speed, draft quality jobs; Letter Quality is

for final, polished documents.

proportional printing

Printing in which the width of the character varies from character

to character. For example, a capital W receives much more space

than a lower case i. The result looks more like a typeset book than

a typewritten draft.

RAM

Random Access Memory. The portion of the printer’s memory used

as a buffer and for storing user-defined characters. All data stored

in RAM is lost when the printer is turned off.

self test

A method of checking the operation of the printer. When the self

test is run, the printer prints out its current DIP switch settings and
