Safety
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 set up 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.
•Place your printer on a firm, solid surface. If you put it on
something unsteady, it may fall and be damaged; if you
place it on a soft surface, such as a rug, sofa, or bed, the
vents may become blocked, causing the printer to overheat.
•To protect your printer from overheating, make sure all
openings on the printer are not blocked. Do not put the
printer on or near a heat source, such as a radiator or heat
register. Keep it out of direct sunlight. Allow enough room
around the printer for adequate ventilation and easy access
to the paper trays.
•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.
•Your printer has an earthed, 3-pin plug as a safety feature,
and it will only fit into an earthed outlet. If you can not
plug it in, chances are you have an older, non-earthed
outlet; contact an electrician to have the outlet replaced.
Do not use an adapter to defeat the earthing.
•To avoid damaging the power cable, do not put anything
on it or place it where it will be walked on. If the cable
becomes damaged or frayed, replace it immediately.
•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 13 amperes.
•The power outlet into which you plug your printer must
remain accessible at all times.
•Lifting the top cover exposes hot surfaces. These are clearly
labelled. Do NOT touch them.
•Do not poke anything into the ventilation slots on the
printer; you could get a shock or cause a fire.
4
OKIPAGE 8c Plus
•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. Always contact your local dealer.
•Do not make any adjustments other than those outlined in
the handbook. You may cause damage requiring extensive
repair work.
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:
•The power cable or plug is frayed or damaged.
•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.

Colour Registration
Each of the four image drums is responsible for producing that
part of the printed image corresponding to its particular colour.
The three primary colours and black are mixed in various
proportions to obtain other colours.
Of course, it is essential that each image drum cartridge produces
its part of the printed image at exactly the right place on the
page relative to each of the others.
If one cartridge, for example yellow, is slightly misaligned you
will notice slight traces of yellow at the edges of other colours
where yellow should not appear. This very precise alignment is
known as colour registration.
Although the four image drums were very accurately aligned
during the manufacturing and testing of your printer, it is
possible that one or more of them may have become slightly
misaligned during shipping. If you notice any symptoms like
that described above, you can easily check and adjust colour
registration using the menus and operator panel controls on
your printer.
These adjustments align the three colour cartridges precisely
to the black cartridge. Your printer has a series of resident test
patterns to help you.
The User’s Guide supplied with your printer contains full
instructions for this and many other adjustments designed to
help you achieve the best possible results from your new colour
printer.

OKIPAGE 8c Plus
Connecting to the PC
The printer comes with a standard high speed bidirectional
IBM Centronics compatible parallel data interface as standard.
This requires a IEEE1284 compliant parallel printer cable, not
more than 1.8m in length. Such a cable has a 36-pin Centronics
style plug at one end (the printer end) and a standard DB25
plug at the other (the PC end).
Two magnetic line filters (1) supplied with the equipment must
be attached to the parallel data cable before connecting the
printer to your host PC.
To attach the filters, position each filter as close as possible to
each end of the cable and snap the filter container shut.
The parallel data cable should be connected to the printer’s
data interface (2) and to the host PCs parallel data port (usually
designated as LPT1).
Optionally you may have a network interface card installed.
This connects directly to your network cable, following the
instructions supplied with the card.
English
Setup Guide17
Installing Windows Printer Drivers
A printer driver is a software program which runs on your PC. It
passes data from your applications suitably formatted for the
printer, and also controls a number of printer functions.
Your printer comes with printer drivers for Windows 3.1x,
Windows 95 and Windows NT4.
If using other operating systems, you could select a printer
driver designed for use with the HP LaserJet IV or HP LaserJet
5. If you have a suitable printer driver for the HP Colour LaserJet
5, this should be used instead.
Windows users should use the drivers supplied with the printer
for best results. These have been designed specially for this
printer, and will make the best use of its many features.
If installing on a network or other printer sharing system, each
PC user should install the appropriate driver for their system.
The CD may contain a README file, containing additional
information too late to be included in the published printer
guides.
The CD package contains instructions for installing the various
Windows drivers and for viewing and printing the on-line
manuals.
