Safety Instructions  
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 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:  
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.  
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.  
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.  
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.  
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 ratings of all equipment plugged into the  
outlet should not exceed 15 amperes.  
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.  
The power outlet into which you plug your printer must remain  
accessible at all times.  
It is recommended that the printer be switched off prior to  
opening or removing covers.  
Do not use your printer near water, or spill liquid of any kind  
on it.

Do not poke anything into the ventilation slots on the printer; This product complies with the requirements of the Council  
you could get a shock or cause a fire.  
Directives 89/336/EEC and 73/23/EEC on the approximation  
of the laws of the member states relating to electromagnetic  
compatibility and low voltage.  
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 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  
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.

Technical Data  
Printing system  
The OKIJET 2500 printer accepts 2 different print heads; a 128 jet  
black only, and a 120 jet segmented four Colour Print Head. The  
system uses a scanning carriage in conjunction with a precision  
paper advance mechanism to position the paper prior to being  
marked by the ink jet.  
Each of the jets is constructed with a heater, a supply of ink in  
the jet and an opening where the ink is expelled. When a  
command is sent to the ink cartridge to place a drop of ink on  
the media, the heater switches on and heats the ink until the ink  
expands into a bubble. As the bubble expands, the ink is then  
expelled out of the nozzle onto the media.  
Ink jet technology  
The heating and expulsion of the bubble of ink takes place in a  
matter of a few nano-seconds.  
The ink jet technology used in the OKIJET 2500 is called a Thermal  
(Bubble) Drop-On-Demand (DOD) Ink Jet. The principles of this  
type of ink jet are as follows:  
All data sent to the printer is converted to raster data. Raster data is  
essentially a string of 1s and 0s that are translated into drops of ink  
across a scan line. As the carriage travels across the media, the  
black and colour ink cartridges place drops of ink on the media as  
directed by the data sent to the printer.  
There are 24 ink jets for each of the three colours (Cyan, Magenta  
andYellow) and 48 for Black, giving a total of 120 jets on the four  
colour ink cartridge. The black cartridge contains 128 ink jets.
