FEATURES / TIPS
Forms Tear-Off
The Forms Tear-Off feature allows a printed continuous forms page to
be torn off without wasting paper or adjusting the printer.
When printing stops, Forms Tear-Off automatically moves the paper to
align the perforation with the tear bar (located under the access
cover), after a time interval which you select through the menu.
Paper remains in the tear-off position until the printer receives more
data. Then, the paper moves back down for printing.
This feature has to be enabled.
Paper Park
Your printer’s paper park feature allows you to print a single sheet
(cut-sheet) page without removing continuous feed paper from the
printer.
For more information, see “Paper Park” in “Using your Printer”.

Top of Form (TOF)
Top of Form (TOF) sets the print start position. The factory default is 1"
from the top.
The TOF can be changed in increments of 1/144", for a single print job
or set to a new default. The overall amount of adjustment is limited to
avoid paper jams.
The first line prints at the red line of the plastic paper shield (1) on the
printhead.

NOTE
The Forms Tear-Off and the Top of Form settings interact. For more
information, see “Top of Form (TOF) and Forms Tear-Off” in “Using your
Printer”.
Turning the Platen Knob
Always turn the printer off before turning the platen knob! If you turn
the platen knob when the printer is on, the Top of Form will misalign.

Controlling Access to the Printer
>
You can control access to the printer by changing the setting
for the Operator Panel Function in the Menu from Full
Operation (the factory default) to Limited Operation.
>
When Limited Operation is selected, the PRINT QUALITY and
CHARACTER PITCH keys don’t work. This prevents these
settings from being changed from the control panel when
several people are using the printer.

INTERFACES - GENERAL
Your printer is equipped with a selection of data interfaces:
Under no circumstances attempt to use both parallel and USB ports
simultaneously.
1.
Parallel – For direct connection to a PC. This port requires a
bi-directional (IEEE 1284 compliant) parallel cable.
2.
USB – For connection to a PC running Windows 98 or above
(not Windows 95 upgraded to Windows 98) or Macintosh.
Windows NT 4.0 does not support USB. Administrator
PRINTER DRIVERS > 10

privileges are necessary for Windows 2000 and Windows XP
installations.
This port requires a cable conforming to USB version 1.1 or
above. A genuine cable displays the Trident symbol on both
connectors.
Using an inferior cable can cause printing problems and
special cables are needed for longer runs than five metres.
The operation of a printer is not assured if a USB compatible
device is connected concurrently with other USB compatible
machines.
When connecting multiple printers of the same type, they
appear as *****, ***** (2), ***** (3), etc. These numbers
depend on the order of connecting or turning on each printer.
CONNECTING THE USB CABLE
Due to the number of possible variants of operating systems it is not
possible to describe every combination.
Terminology may vary between Windows operating systems and some
knowledge is assumed. If you are unsure how to proceed, you should
consult your computer documentation or system manager for details.
This example uses Windows 2000 Professional.
1.
Ensure the printer and computer are easily accessible and turn
both units off. This is not strictly necessary but may prevent
any problems being caused by the accidental dislodging of
power or other cables.
2.
Plug the Series A male connector (a) into
the the computer’s USB port or into a
suitable USB hub.
b
3.
4.
Plug the Series B Male connector (b) into
the printer’s USB port.
a
Switch on both the computer and printer.

6.
The printer will be identified
immediately by the New Hardware
Wizard and install itself in the Printer
folder. An additional item, USB Printing
Support will also appear in the Device
Manager each time the printer is
switched ON and connected.
Check that the default paper size has
been correctly set by looking at the
settings in the Settings > Printers folder.
Under the printer's Properties > General
tab, the current paper selection is
shown. The printer picks up its initial
setting from the Locale settings on the
host computer. The paper size can be
altered by using the drop down arrow
and selecting an alternative size.
7.
If the printer had formerly been used as a parallel or serial
device and there is no output from the printer once a USB
cable has been connected, check to see that the correct port
has been selected. This information can also be found in the
Properties folder but under the Ports tab. Amend as necessary.
8.
9.
If there are printing problems, check to see whether there is a
USB connection active in the Control Panel. If there is no USB
connection shown, you must install the hub.
Alternatively, there may be a problem if the printer is
connected via a USB hub. Disconnect the printer cable from
the hub and connect it directly to the computer.

FORMS TEAR-OFF FEATURE
This feature is normally turned off. To use Forms Tear-Off, you must
enter the menu and change the setting to the desired time interval
(see “Changing the Forms Tear- Off Settings”).
The Forms Tear-Off feature allows a printed continuous forms page to
be torn off without wasting paper or adjusting the printer. It can be
used for rear feed continuous forms, bottom feed continuous forms
(with the optional push tractor installed), or for top feed roll paper
(with optional roll paper stand installed).
When the printer is turned on, the paper feeds to the tear-off position.
USING YOUR PRINTER > 18

When data is received, the paper automatically moves down to the
print position (TOF) and printing begins.
NOTE
You can also move the paper down to the print position manually by
pressing TEAR.
When printing stops, Forms Tear-Off automatically moves the paper to
align the perforation with the tear bar (located under the access
cover), after the time interval which you selected through the menu.
Paper remains in the tear-off position until the printer receives more
data. Then, the paper moves back down for printing.
NOTE
>
The status of the Forms Tear-Off menu setting affects how you set
the Top of Form: see “Top of Form (TOF) and Forms Tear-Off” earlier
in this chapter.
>
>
Do not use Forms Tear-Off with labels or multipart forms!
Forms Tear-Off cannot be used when the optional pull tractor is
engaged.
POTENTIAL ISSUES WITH SOFTWARE PACKAGES
If Forms Tear-Off is set to ON and the software package you are using
“pauses” for a long enough interval while sending data to the printer,
Forms Tear-Off may be activated. No data is lost, but this causes
uneven print registration due to the paper movement.
If this occurs, use the menu to turn off this feature, then use the TEAR
key to move the paper up to the tear position manually (see
“Changing the Forms Tear-off Settings”).

CHARACTER PITCH
1
Character pitch determines how many characters will print on each
line. You can choose a specific fixed width for each character in
characters per inch (cpi), or Proportional. The higher cpi settings are
often used for spreadsheets.
Proportional (PROP) sets character widths based on the character
itself: e.g., the letter i is assigned a narrower width than the letter m.
This provides a more polished, typeset appearance.
NOTE
Front panel settings for character pitch are normally overridden when
the SI command is received from your software.
EPSON AND IBM EMULATIONS
Set the character pitch by pressing CHARACTER PITCH (1) until the
light beneath the desired setting is illuminated:
l
10 cpi; 12 cpi; 15 cpi; 17 cpi; 20 cpi or Proportional
MICROLINE Emulation
In the MICROLINE emulation, the Character Pitch choices are:
l

EXPLANATION OF MENU ITEMS
These explanations are in alphabetical sequence to make it easier to
look them up. Some items only appear when optional accessories are
installed; others appear in several groups in the menu.
7 or 8 Bit Graphics, Default = 7
Change this setting to 8 if your system uses 8-bit graphics.
7 or 8 Bit Data Word, Default = 8
Change this setting to 7 if your system uses 7-bit data word lengths.
Auto CR, Default =No
IBM emulation only. If you want the printer to automatically add a
carriage return when a Line Feed is received at the end of a line,
change the setting to Yes.
Auto LF, Default = No
If your printout is consistently double spaced, select No; if it
overprints, select Yes.
Auto Feed XT, Default = Invalid
Epson emulation only. In the Epson emulation, the XT signal on pin 14
of the parallel interface can control automatic line feed. Some
interface cables are wired in such a way that automatic line feed is
always in effect: this item eliminates this potential problem. If your
system uses pin 14 of the parallel interface to control automatic line
feed, change the setting to Valid.
Auto Select, Default = No
Determines whether or not your printer will automatically be selected
after you load in paper. With the factory default engaged, the printer
will be deselected so that you can set the Top of Form. If you always
use the same Top of Form position, change the setting to Yes.

overridden by the software’s settings when the I-Prime signal
is sent.
Language Set, Default = ASCII
Replaces certain standard symbols with special characters used in
foreign languages.
Line Spacing, Default = 6 lpi
Change to 8 lines per inch (lpi) to get more lines on a page.
Operator Panel Function, Default = Full Operation
Change to Limited Operation to deactivate the PRINT QUALITY and
CHARACTER PITCH buttons, so that these features can only be
controlled through your software. This prevents these from being
changed from the control panel when several people are using the
printer.
NOTE
This feature also prevents access to the Menu. To access the Menu in
these circumstances, turn the printer off, then hold down the SEL key
while turning ON the printer.
Page Length, Default = 11-2/3" or 1/2"
Selects the length of the paper you are using. This enables the printer
to keep track of the initial printing position (TOF) on each page.
Page Length Control, Default = by Actual Page Length
If you wish to use the Paper End sensor to detect the actual paper end,
use Actual Page Length setting. If you use “by Menu Setting”, the
printer will disregard the Paper End (PE) and use the page length as
set by the menu.

printhead by allowing printing without paper.
Parity, Default = None
Appears only when the optional Serial Interface is installed. Selects
the type of parity your system uses: None, Odd or Even.
Pin 18, Default = +5V
Sets the signal on pin 18 to +5 volts or open.
Pitch, Default = 10 cpi
Choose the character width in characters per inch (cpi).
Power Save Time, Default = 5 min.
Sets the interval the printer waits for more data before it goes into the
power save mode. Power Saving must be set to Enable (the factory
default) for this to be effective.
Power Saving, Default = Enable
Change to Disable if you wish to prevent the printer from entering the
Power Save mode after the selected interval.
Print Mode, Default = Utility
Choose the quality and typeface of printing. Switch to NLQ Courier or
NLQ Gothic for Near Letter Quality printing. If you are printing
draft-type documents, select DRAFT, then select either HSD or SSD
under DRAFT Mode. Both of these Items are in the Font Group.

Print Registration, Default = 0
Change the setting as required to obtain the best registration for bi-
directional printing.

Selects the amount of memory devoted to holding received data.
Choosing 1 Line will tie up your computer while printing, but if you
abort the print job, the printer will stop much sooner.
Reset Inhibit, Default = No
Select Yes if you wish the printer to ignore the reset command sent by
software. This prevents your software from changing the settings you
make through the front panel controls or through printer commands.
NOTE
This will also prevent your software from clearing out existing settings
when you finish printing one document and switch to another.
Serial Data 7/8 Bits, Default = 8 Bits
Appears only if the optional Serial Interface is installed. Change to 7
Bits if your system uses a 7-bit data format.

IBM emulation only. Sets the pitch to be engaged when the printer
control panel is set for 12 cpi and the SI command is received.
Size, Default = Single
Change to Double for double width and height printing.
Skip Over Perforation, Default = No
Change to Yes if you want the printer to go to the next page when it
comes within 1" (25 mm) of the bottom of the page. Keep it set to No
if your software has its own page formatting controls.
Style, Default = Normal
Change to Italics if you want the printed characters to be slanted.
Time Out Print, Default = Valid
If your software spends a long time processing between portions of
data it feeds to the printer, change the setting to Invalid to keep your
printer from dumping the received data while it is waiting for more.

TROUBLESHOOTING
GENERAL INFORMATION
Here are some general things to check before proceeding with
detailed troubleshooting.
l
l
l
Is the printer plugged in and turned ON?
Are the connections (power and interface) secure?
Is the product being operated under the proper ambient
conditions?
l
Does the paper being used meet the specifications for this
product?
l
l
l
l
l
Is the paper properly installed?
Is the ribbon properly installed?
Is an Oki ribbon being used?
Is the printhead gap correctly set?
Are the correct printer drivers being used for the printer?
NOTE
>
>
Settings in your software application will normally override any
settings in your printer driver.
Printer driver settings normally override settings from the printer
menu or printer front panel.
Problem
My word processor files do not print the way I have the menu and front
panel set.
Solution
Remember:
l
Settings in your software application can override settings in
your printer driver.
TROUBLESHOOTING > 63
Download from Www.Somanuals.com. All Manuals Search And Download.
l
Your printer driver settings can override any settings from the
printer menu or printer front panel.
Before sending a file to the printer, many word processors send either
an “initialization string” or an I-Prime signal to the printer.
The initialization string contains codes that override the panel and
menu settings. To change your printer to ignore the reset code, enter
the Menu Mode, go to the Set-Up group and change the setting for
Reset Inhibit to Yes.
The I-Prime signal will automatically override any front panel settings
you have made. To eliminate this problem, enter the Menu Mode, go
to the Parallel Interface group and change the setting for I-Prime to
Invalid.
For more information on changing menu settings, see “Changing the
Menu Settings” in Chapter 3.
Problem
Nothing happens when I turn ON the printer.
Solution
Check the power cord connection to the outlet and to the printer. If
you are using a power strip, make sure it is turned ON, and that the
fuse hasn’t blown or that the circuit breaker hasn’t tripped.
Problem
The printer does not print when the computer sends data.
Solutions
1.
2.
Is the SEL light on? If not, press the SEL key.
Check that the interface cable is securely connected to both
the printer and the computer.
3.
If you have the optional serial interface board installed, check
to be sure that it is firmly seated in the printer.

Problem
I'm getting strange symbols, incorrect fonts, etc., when I try to print a
document.
Solutions
1.
Check to be sure that the printer driver you have selected in
your software matches the printer emulation.
2.
Press SHIFT and SEL keys, then press GROUP key.
This will print a line showing the emulation you have selected.
3.
If you have embedded any printer commands in your software,
check to be sure that you entered them correctly.
Problem
Ink smears on the paper when I print narrow columns.
Solution
This may be caused by excessive printhead travel from the centering
position. Enter the Menu and set the Centring Position to MODE 1. See
“Using Your Printer, Menu Mode.”
For the wide carriage printer, if MODE 1 doesn't work, try setting the
Centering Position to MODE 2.
Problem
I've installed a new ribbon and the printing is smeared and streaked.
Solution
The ribbon shield (1) is either loose or missing.
1
Remove the ribbon cartridge and check the ribbon shield.
If it is loose, secure it.
If it is missing, find it and install it.

Problem
There are dots missing in my printouts.
Solution
The head gap may not be set correctly. Try moving the headgap lever
to a lower setting. If that doesn’t help, the printhead may be
damaged; call for service.
Problem
The ALARM light is flashing.
Solution
Try turning the printer OFF and then back ON again. If the light still
blinks, call for service.
Problem
The ALARM light is ON and the Character Pitch 10 light is flashing.
Solution
This indicates that the paper lever is set at the wrong position for the
paper you are trying to use. Move it to the proper setting.
Problem
The ALARM light is ON and the Character Pitch 15 light is flashing.
Solution
This indicates a paper jam. Press the SEL key and correct the paper
jam situation. See “Clearing Paper Jams,” in Chapter 3.
Problem
The printer needs paper. The ALARM is not ON and I can’t load paper.
Solution
1.
2.
Press and release the SEL key.
Press and hold the SHIFT key and press the RESET /
CHARACTER PITCH key.
The ALARM light illuminates and you can now load paper.

Problem
Continuous-form paper sticks to the sheet guide.
Solution
In cold dry weather, static charges can build up and make the paper
cling to the sheet guide. Try moving the paper guides together so that
the paper rests on the guides rather than on the separator.
Problem
The Print Quality and Character Pitch keys on the front panel don't
work.
Solution
The Operator Panel Function in the printer menu can be used to
disable these buttons (Limited Function). If the printer is part of a
customized system or if it is used by a number of people, the system
manager may have used this option to make sure the printer is always
set properly.
Check with your system manager before changing any menu settings.
