Safety Instructions
Your Oki printer has been carefully designed to give you years
of safe, reliable performance. As with all electrical equipment,
however, there are a few basic precautions you should take to
avoid hurting yourself or damaging the printer:
•Read the setup instructions in this handbook carefully.
Be sure to save it for future reference.
•Read and follow all warning and instruction labels on the
printer itself.
•Unplug the printer before you clean it. Use only a damp
cloth; do not use liquid or aerosol cleaners.
•Do not use your printer near water, or spill liquid of any
kind into it.
•Be certain that your power source matches the rating listed
on the back of the printer. If you are not sure, check with
your dealer or with your local power company, or use the
appropriate Oki power supply unit.
•The power outlet into which you plug your printer must
remain accessible at all times.
•If you are using an extension cable or power strip with
the printer, make sure that the total of the amperes required
by all the equipment on the extension is less than the
extension’s rating. The total ratings of all equipment
plugged into the outlet should not exceed 15 amperes.
•Aside from the routine maintenance described in this
handbook, do not try to service the printer yourself;
opening the cover may expose you to shocks or other
hazards.
If anything happens that indicates that your printer is not
working properly or has been damaged, unplug it immediately
and contact your dealer.
These are some of the things to look for:
•Liquid has been spilled into the printer, or it has been
exposed to water.
•The printer has been dropped, or the cabinet is
damaged.
•The printer does not function normally when you are
following the operating instructions.

Testing the Printer
You can test the printer to ensure that it is running properly.
The sample on the following page shows what a printout of the
test may look like. The test pattern varies depending on the
printer model and the character set selected when the printer
was ordered.
Run the test after loading the paper, but before connecting it to
a host system. If the characters do not print properly, check to
make sure the paper is installed correctly, and that suitable
thermal paper is being used.
If the printer is still not working correctly, contact your dealer.

Cleaning the Printer
The keypad contains one button and one status LED for easy
operation of the printer.
Status LED
There is a single status LED to display on-line and error
conditions. The following table describes the types of error
conditions possible and patterns that the LED will flash in those
conditions.
16OKIPOS 80 Plus III
Cleaning the printer occasionally and keeping it well maintained
will help it to last longer and run better.
Do not use rubbing alcohol or any kind of cleaner on any
internal parts of the printer, as some parts may crack or
break as a result.
80p3gb.p6512/01/99, 11:4316
Cleaning the Thermal Printhead
Under normal conditions the thermal printhead does not need
cleaning.
If the print characters are not printing correctly, wipe the thermal
printhead with alcohol and a lint free cloth.
Do not get any alcohol on any of the other parts of the
printer mechanism or the casing.
