Safety Instructions
Your Oki printer has been carefully designed to give you years of
safe, reliable performance. As with all electrical equipment, how ever ,
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.
• 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.
• T o protect your printer from o verheating, make sur e 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
on 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 cannot 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 or damaged. 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 current (amperes) required by
all the equipment on the extension is less than the extension’s
rating. The total r atings of all equipment plugged into the outlet
should not exceed 15 amperes.
• The power outlet into which you plug your printer must remain
accessible at all times.
• Do not poke anything into the ventilation slots on the printer;
you could get a shock or cause a fire.
English
5Read Me First
• 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.
• Lifting the top cover exposes hot surfaces. These are clearly
labelled. Do NOT touch them.
• Do not make any adjustments other than those outlined in the
handbook since 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 e xposed
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.
