ADJUSTING THE HEAD GAP
The head gap is the distance between the print head and the platen
roller. When you use envelopes or multi-part forms you will need to
have a larger gap than when using plain paper. Use the recommended
head gap to ensure the best print quality and easy paper feed.
To adjust the print head gap, move the coloured lever located to the
left of the ribbon cartridge (a), to the correct position for the type of
stationery being used……
…..as detailed in the following table:
CAUTION!
Incorrect setting of the print head gap can cause print head damage
or ribbon jams. To avoid these problems set the print head gap for the
type of stationery being used.

PRINTER DRIVERS
Printer drivers enable your computer to communicate with the printer.
As with most printer manufacturers, Oki creates printer drivers for use
with popular types of software, such as Microsoft Windows operating
systems, from Windows 95 onwards. Installing a printer driver is
normally a simple process of making a selection within the software.
If a driver is not available by name for your printer, contact the
software manufacturer and ask if they can supply an updated version
of their software with additional drivers. Alternatively, check the
driver availability on the Oki Europe Web Site at:
www.okieurope.com
If you are using bespoke software or software created specifically for
your company, it is unlikely that the CDs supplied with this software
will include drivers for your printer. In this instance you will have to
choose a driver as closely compatible as possible. Compatible drivers
contain printing codes that will operate your printer. They may not
offer the special features of an original driver, but they will allow you
to perform normal printing tasks.
Oki’s printers contain more than one printer emulation selectable via
the menu system. See the table below for compatible drivers.
However, please note that the emulations listed toward the bottom of
this list are more basic and offer fewer of the printer’s features.

5. Insert the paper stack into the hopper and push it against the
left paper guide, making sure that the paper fits under the
corner separators.
6. Adjust the right paper guide to the paper width.
7. Push both paper guide locking levers upward into the locked
position.
8. Push the paper set lever (1) gently backward into the set

MANUAL LOADING WITH THE CUT-SHEET FEEDER INSTALLED.
1. Gently insert the paper from directly above the front sheet
support.
2. Use the FORM FEED button to feed the sheet.
3. Turn the Platen knob clockwise/anti-clockwise for fine
adjustment.
NOTE
The manually set sheet is printed automatically, even when other sheets
are loaded in the hopper. When the FORM FEED button is pressed, the
manually inserted sheet will be fed from the cut-sheet feeder.
CAUTION!
l Do not manually feed paper if a sheet is being fed from the
hopper. Simultaneous feeding of paper will result in a paper
jam.
l To manually feed a sheet of paper, you must use the FORM FEED
button to feed the paper. If the paper is being fed manually and
is positioned using the platen knob rather than the FORM FEED
button, it may be ejected just before printing begins (use the
Platen Knob for fine adjustment only).

OPERATING YOUR PRINTER > 35
CUT-SHEET FEEDER CONTROLS
The printer’s control switches also control the operation of the cut-
sheet feeder. The control switches, however, function only when the
printer is off-line or deselected (SELECT indicator is not lit).
USING THE ROLL PAPER STAND (IF FITTED)
LOADING THE PAPER
1. Open the paper separator all the way.
2. Remove the paper roller.
Note that there is a disk on the left end of the roller.
3. Slide the roller into a tube of paper.
Ensure the disk is on the left side and paper must roll up from
the bottom.
4. Replace the paper roller back into the stand, with the disc on
the left side.
5. Feed the paper over the roller on the stand. NOT UNDER!
6. Adjust the round paper guides at either side to the paper
width.

Page: 35

OPERATING YOUR PRINTER > 36
7. Feed the paper down behind the platen and use platen knob to
bring paper through the printer.
Lift the bail arm as paper comes round to front of platen. (The
paper release lever needs to be in the top position to perform
this step).
8. Continue to feed the paper through for approx. 4 inches.
9. Move the paper release lever toward the front of the machine.
Align the paper so that the exit and entry paper edges align.
Return the paper release lever to the rear position to re-apply
pressure on platen.
10. Close the bail arm.
11. Replace the access cover. Fit the cover tabs into the slots at the
printer front. Lower the cover carefully, making sure the paper
fits through the front slot in the access cover.
12. Lower the paper separator so that paper enters the printer
from under the separator and exits the printer going over the
separator (see below).
13. Turn the platen knob to move the paper to the point where you
want printing to start. (Many word processing packages
automatically allow for a top margin of 25.4mm (1 inch)).

TROUBLESHOOTING
GENERAL INFORMATION
Here are some general things to check before proceeding with
detailed troubleshooting.
> 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?
> Does the paper being used meet the specifications for this
product?
> 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?
Problem
My word processor files do not print the way I have the menu and front
panel set.
Solution
Remember: The note above!
Before sending a file to the printer, many word processors send either
an “initialization string” or an I-Prime signal to 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.

Page: 38

> 39
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. If the
solution is not obvious — call for service.
Problem
The printer does not print when the computer sends data.
Solutions
1. Is the SEL light on? If not, press the SEL key.
2. 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 and that the
interface cable is securely connected to both the printer and
the computer.
Problem
I’m getting strange symbols, incorrect fonts, etc., when I try to print a
document.
Solutions

Page: 39

> 40
1. Check to be sure that the printer driver you have selected in
your software matches the printer emulation.
2. Please refer to the Printer Driver section for details of
emulations, then check the menu settings (see “Setting Printer
Defaults” in the Operating your Printer section).
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.
Solutions
The head gap could be too close. Check that the head gap is set
correctly (see the table in “Adjusting the head gap” in the Getting
Started section).
Problem
I’ve installed a new ribbon and the printing is smeared and streaked.
Solution
The ribbon shield (1) is either loose or missing.
Remove the ribbon cartridge and check the ribbon shield.
If it is loose, secure it. If it is missing, find it and install it. If you
cannot find it, replace the ribbon cartridge.
Tip: If you still have an old ribbon cartridge, remove the shield
from it and install it on the ribbon cartridge on your printer.
Problem
There are dots missing in my printouts (typically, tops and /or bottom
of characters missing).
1

Page: 40

> 41
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 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.
Problem
My printer keeps indicating “Paper out” when there is paper installed.
Solution
The most likely cause is that the paper sensor groove in the platen is
not being covered by paper. Re-align paper to cover the sensor
groove.
Problem
When I am using continuous feed paper, the sprocket holes are torn,
causing alignment problems.
Solution
The most likely cause is that the paper lever is set to friction feed.
Move the lever to “Fan-fold” (to the front of the printer)
