ADJUSTINGTHE 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.
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.
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......

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 Server 2008/Windows
7 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 Data global Web Site at:
http://www.oki.com/printing/
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.

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?
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: 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.
TROUBLESHOOTING > 36
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.
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.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).
TROUBLESHOOTING > 37
3.If you have embedded any printer commands in your
1
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).
TROUBLESHOOTING > 38
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).
