Your OKI printer has been carefully designed to give you years 
of safe, reliable performance. As with all electrical equipment, 
there are a few basic precautions you should take to avoid 
hurting yourself or damaging the printer.
• Carefully read the provided setup and operating instructions.
• Save all provided documentation for future reference.
• Read and follow all warning and instruction labels on the 
printer itself.
• The printhead can get quite hot when it has been printing for 
a length of time. Do not touch the printhead until it has had a 
chance to cool off.
• 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 cushion, the vents 
may be blocked, causing the printer to overheat.
• Protect your printer from overheating. Make sure no 
obstructions block the openings of the printer. Do not put the 
printer on or near a heat source (such as a radiator or heat 
register). Keep the printer out of direct sunlight.
• Always use this printer in a well ventilated area. Allow 
enough room around the printer for adequate ventilation and 
easy access to the paper trays. If you put the printer in any 
kind of enclosure, make sure the enclosure is well ventilated.
• Do not use your printer near water. Do not 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.
• Do not connect this product to an uninterruptible power 
supply (UPS). For further information please contact Oki Data 
at 1-800-OKI-DATA or 
www.okiprintingsolutions.com
.
• Your printer has a grounded, three-prong plug as a safety 
feature. This plug only fits into a grounded outlet. If the plug 
does not fit, the outlet may be an older, non-grounded type. 
Contact an electrician to have the outlet replaced. Do not use 
an adapter to defeat the grounding.
• Install the printer near an easily accessed power outlet.
• 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.
• Do not poke anything into the ventilation slots of the printer. 
You could get an electrical shock or cause hazardous 
electrical arcing, which could cause a fire.
• Aside from the routine maintenance described in the 
documentation, do not try to service the printer yourself. 
Removing the cover may expose you to shocks or other 
hazards. 
• Do not make any adjustments other than those outlined in 
the documentation. You may cause damage that will require 
extensive repair work. The provided documentation explains 
how to get your printer serviced by qualified Oki Data 
technicians.
If anything happens that indicates that your printer is not 
working properly or has been damaged, unplug it immediately 
and follow the procedures in the provided documentation for 
having your printer serviced. 
Here are some of the things to look for.
• The power cord or plug is frayed or damaged.
• Liquid has been spilled into the printer, or the printer 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.
