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:  
• 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.  
• 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 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.  
• 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 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.  
• 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.  
• Lifting the top cover exposes hot surfaces. These are clearly  
labelled. Do NOT touch them.  
• Do not insert anything into the ventilation slots on the  
printer; you could get a shock or cause a fire.  
• Do not use your printer near water, or spill liquid of any  
kind into it.

• 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.  
• It is recommended that the printer be switched off prior to  
opening or removing covers.  
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.

sometimes cause very heavyweight paper or cardstock to jam  
or misfeed.  
2. Insert the envelope, flap down and to the left, until the  
printer grips it.  
3. Set envelope size and landscape orientation in your  
software, then issue the print command.  
Choosing Envelopes  
• Always use rear output.  
• No windows or metal clasps.  
• Media no heavier than 28 lbs.  
• Smooth even surface.  
Use the front tray to feed this type of paper and the rear paper  
exit to collect your printed output. This gives a nearly straight  
paper path through the machine, and may prove more reliable  
in this type of application.  
• No self-sealing flaps.  
• Seams down the sides, not across the middle.  
• Squared-off flaps that do not cover the print area.  
Print Quality Adjustments for Different Paper  
The process used to fuse (fix) the printed image to the paper  
involves a mixture of pressure and heat. Too much heat will  
cause lightweight paper to crease or curl, while too little heat  
will cause the image not to fuse fully into heavyweight paper.  
Printing Transparencies  
Select and print transparencies using the MANUAL FEED  
option under MEDIA TYPE in MENU 1. Select TRANSPR to  
ensure the correct fusing temperature is set. Damage may  
occur to your transparencies if an incorrect setting is used.  
Use the MEDIA TYPE setting in MENU 1 to adjust for different  
thicknesses of paper.

Toner  
When to Replace the Toner Cartridge  
Replacing the Toner Cartridge  
Do NOT remove cartridge from packaging.  
Replace the toner cartridge after TONER LOW displays in the  
printer control panel window. After TONER LOW displays,  
the printer will print about 100 more pages, then display  
TONER EMPTY and stop printing. Printing will resume after a  
new toner cartridge has been installed.  
Use OKI Type 5 image drum and toner cartridges only.  
1. Open the cover and remove the used toner cartridge.  
TheuseofOKItonerishighlyrecommended.Usingcompatibleor  
counterfeittonerscanseriouslydamageyourprinter.  
Toner Cartridge Life  
How long your toner cartridge lasts depends on the print  
density; the percentage of the page that prints black. A typical  
letter has 3% to 5% print density; graphics usually have higher  
density. Higher print density means toner is used up faster.  
At 5% print density, a toner cartridge will print an average of  
2,000 pages. Remember, this is only an average: actual results 2. Shake the toner cartridge to evenly distribute toner.  
may vary.  
The first toner cartridge in your new printer has to fill the drum  
reservoir and saturate the developing roller with toner. It  
normally produces about 1,000 pages.

Image Drum Cartridge Life  
• Do not expose the drum to direct sunlight and do not  
expose it to room light for more than 5 minutes. Leave it  
in the package until you are ready to install it into the  
printer.  
The life of an image drum depends on a number of factors,  
including temperature and humidity, the type of paper you  
use, and the number of pages per job.  
The image drum cartridge should last about 9,000 pages at one  
page per job, 14,000 pages at three pages per job and 20,000  
pages at fifteen pages per job. These numbers are approximate,  
since you do not print the same number of pages each time, and  
environmental conditions and paper type used may vary.

What Is a Font?  
2. Press the TRAY TYPE/Print Fonts button for at least two  
seconds. The display shows FONTS HP PCL6  
.
Strictly speaking, a font refers to a set of printable characters  
in a particular typeface of a specific size (e.g. 12 point) and  
style (e.g. roman, bold or bold-italic). In computer printing,  
however, this term has been used in a wider context to refer  
to all sizes and styles of a particular typeface. In printers,  
fonts may be divided into two basic types: bitmap fonts and  
scalable (or outline) fonts.  
3. Press the ENTER button.  
4. After a short delay two pages of font information will be  
printed, including samples.  
Using Fonts  
Bitmap fonts are made up of a pattern of dots (at the printer  
resolution) to form the image of each printable character. These  
are of a fixed size, and scaling makes them look ragged.  
Some MS-DOS and most Windows programs provide an easy  
method of font selection within documents. In these cases the  
printer’s font selection is controlled by the host PC software  
application (or by Windows itself). On other software platforms  
special codes (escape sequences) must be embedded with the  
print data. This topic is beyond the scope of this Help Guide.  
However, the font list referred to in the previous topic contains  
a list of the required codes. Use of these codes is best left to a  
professional programmer.  
Scalable fonts are stored as a set of mathematical curves. At  
print time the printer uses the stored curves to make up a  
bitmap of each character required, at the required size, and  
in the required style, at the full printer resolution. Such fonts  
are therefore said to be scalable, and do not appear ragged at  
enlarged sizes.  
Symbol Sets  
Your printer provides special sets of characters for technical,  
legal and foreign language uses, as well as sets of drawing  
characters and standard alphanumeric characters. Each font  
uses symbols from one or more of these sets.

Software Problems  
Your software (operating environment, applications and printer drivers) controls the printing process. Make sure you have  
selected the right driver for use with your printer. See your software documentation for more information.  
Symptom  
Problem  
Solution  
Printing is “garbled”.  
Incorrect driver is installed.  
Install an appropriate driver.  
Printer’s output is below rated  
speed.  
Much of the printing delays will be caused by  
your application. Sometimes purely text  
documents will print slowly depending on the  
selected fonts and how they are transferred to  
the printer.  
For maximum speed, use text in your  
document and use a printer resident font.  
Size of top margin increases  
with each page printed.  
“Creeping text.” Number of lines per page in  
software is not equal to number of lines per page  
of printer.  
Many software packages assume 66 lines  
per page, but your printer’s default is 64.  
Adjust software accordingly, or set LINES Per  
PAGE in the soft control panel to equal lines  
per page in your software.

Hardware Problems  
Symptom  
Problem  
Solution  
Graphic image prints partly on  
one page, partly on the next.  
Insufficient printer memory for this image at this  
resolution.  
Change the resolution, reduce the image  
size, or install more memory in your printer.  
When you try to print nothing  
happens, but printer indicates  
it is ready to receive data.  
Configuration error.  
Check cable connection. If more than one  
printer is available, make sure your printer  
has been selected.  
“Garbage” prints.  
Incorrect cable configuration.  
(Also, see “Software Problems.”)  
Check cable configuration, continuity, and  
length.  
Printer freezes or displays  
error message when computer  
is rebooted.  
Booting the computer while the printer is on can  
cause a communications error.  
Turn printer off before rebooting computer.  
Odours.  
Gases are given off by forms or adhesives  
passing through the hot fusing unit.  
Make sure the forms you use can withstand  
heating, and provide adequate ventilation.  
Printer is on but must “warm  
up” before a job is printed.  
Power Save mode is set on to conserve energy.  
The fuser must heat up before you can begin  
printing the next job.  
To eliminate warm up delay, change Power  
Save setting in the soft control panel.
