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 book carefully . Also read
the Help Guide for further information. Be sure to save these
manuals 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. 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 supplier.
•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, you probably have an older , non-earthed outlet; contact
an electrician to have the outlet replaced. Do not use an
adapter to defeat the earthing.
•This printer must be installed near to a power outlet switch
which shall remain easily accessible.
•To avoid damaging the power cord, do not put anything on
it or place it where it will be walked on. If the cord becomes
damaged or frayed, replace it immediately.
•If you are using an extension cord 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.

Important Wiring Instructions
•Do not poke anything into the ventilation slots on the printer;
you could get a shock or cause a fire.
•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.
•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.
The wires in the power cable are coloured in accordance with
the following code:
Green and Yellow.......Earth
Blue .............................Neutral
Brown .........................Live
If the colours of the wires in the power cable of this printer do
not correspond with the markings of the terminals of your plug,
proceed as follows:
•Green and Y ello w must be connected to the terminal marked
with the letter E (or the safety earth symbol) or the terminal
coloured Green or Green & Yellow.
•Brown must be connected to the terminal marked with the
letter L or coloured Red.
•Blue must be connected to the terminal marked with the
letter N or coloured Blue or Black.
Warning: This printer must be earthed.
If you are in any doubt regarding the wiring, please contact a
qualified electrician.
