This printer has been carefully designed to give years of
safe, reliable performance. As with all electrical equipment, however, there are a few basic precautions t hat
should be taken to avoid personal injury or damaging
the printer:
•Read this user’s guide carefully and save it for
future reference.
•Read and follow all warning and instruction
labels on the printer itself.
•Disconnect the printer before cleaning. Use only
a damp cloth. Do not use liquid or aerosol cleaners to clean the printer.
•Place the printer on a firm, solid surface. If the
printer is placed on something unsteady, it may
fall and become damaged or injure someone. If
the printer is placed on a soft surface, such as a
rug, sofa, or bed, the vents may become blocked
causing the printer to overheat.
•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.
•Do not use the printer near water, or spill liquid
of any kind into it.
•Make sure that the 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.
•This printer has an earthed plug as a safety feature and will only connect to an earthed outlet. If
this plug cannot be connected to a power outlet,
then it is possible that the power outlet is of the
older, non-earthed type. Contact an electrician to
have the power 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. If the cable becomes damaged or frayed,
replace it immediately.
•If an extension cable or power strip is being used
with the printer, make sure that the total of the
amperage rating required by all the equipment is
less than the rating of the extension cable or
power strip. The total ratings of all equipment
User’s Guide1
Page 8
plugged into the outlet should not exceed 13
amperes.
•The printer has been dropped, or the cabinet is
damaged.
•The power outlet into which the printer is connected must remain accessible at all times.
•Opening any cover may expose hot surfaces.
These are clearly labelled. Do NOT touch them.
•Do not insert anything into the ventilation s lots
on the printer; you could get a shock or cause a
fire.
•Aside from the routine maintenance described in
this user’s guide, do not try to service the printer
yourself. Opening a cover may expose you to
shocks or other hazards.
•Do not make any adjustments other than those
outlined in this user’s guide as damage may be
caused to the printer.
If anything happens tha t in di cates t h at the pr in te r is not
working properly or has been damaged, disconnect the
printer from the power source 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 does not function normally when following the operating instructions.
Toner cartridge and image drum
handling
•Leave unused toner cartridges and image drum
units in their packages until needed. When
replacing a toner cartridge or image unit, reuse
the packaging to dispose of the old tone r cartridge
or image drum unit.
•Do not expose the toner cartridges and image
drum units to light for more than five minutes.
Never expose the green drum (inside the image
drum unit) to direct sunlight.
•Always hold the image drum unit by the ends never by the middle. N ever touch th e green drum
inside the image drum unit.
•To avoid damage to the image drum unit, always
use original toner cartridges.
•Exercise care when removing the toner cartridge.
Do not let it touch your clothing or porous materials. The toner powder causes permanent stains.

Print quality adjustments
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
and corrugations in transparencies. Too little heat wi ll
cause the image not to fuse fully into heavyweight paper.
The print quality for different types of paper is set by
default according to the paper size. If thinner o r th icker
paper is being used, the thickness setting can be adjusted as follows:
1.Open the Chooser from the Apple menu.
2.Click on the printer icon that is being used, then
click on the Preferences button.
3.Click on the Print button and then click on the
Advanced button.
4.Click on the box next to Thickness and select the
required thickness of paper.
5.Click on OK button, then Preferences button and
finally the OK button.

Toner
English
When to replace toner cartridge
After the message Toner Low displays, the printer will
print about 100 more pages, then display the message
Toner Empty and stop printing. Printing will resume after a new toner cartridge has been installed.
CAUTION:
The use of original toner or toner cartridges is highly
recommended. Using compatible or counterfeit toner or
toner cartridges can seriously damage the printer.
Toner cartridge life
How long your toner cartrid ge lasts depends on the
print density; the percentage of the page th at prints
black. A typical letter has 3% to 5% print density;
graphics usually have higher density. High er print density means toner is used up faster. At 5% print density,
a toner cartridge will print an average of 1500 page s.
Remember, this is only an average: actual results may
vary.
The first toner cartridge installed in a new printer has to
fill the image drum reservoir and saturate the develop-
ing roller with toner. The firs t toner cartridge normally
produces between 500 and 700 pages after installation.
Replacing toner cartridge
WARNING
Be careful when handling the toner cartridge. Do not let
toner spill on your clothing or other porous materials.
1.Open the cover and remove the used toner cartridge.
2.Shake the new toner cartridge to evenly distribute
toner.
3.Unwrap the new toner cartridge and carefully
peel off the sealing tape (1).

Image drum
English
When to replace image drum
As the image drum approaches its end of life, a Change
Drum message appears. Change the image drum when
the print quality becomes faint or begins to deteriorate.
Image drum life
The life of an image drum depends on a n umb er o f fac tors, including temp erature and humidi ty, the type of
paper used, and the number of pages per job.
The image drum should last abou t 10,000 pa ges continuous printing and up to 8,000 pages at 3 pages per job
(without power save). These numbers are approximate
because different number of pages are printed each time
and the environmental conditions and the paper type
used may vary.
Replacing image drum
1.Open the cover and remove the used image drum.
CAUTION:
Never expose the image drum unit to light for more than 5
minutes. Never expose the image drum unit to direct
sunlight. Always hold the image drum unit by the ends.
Never touch th e surfac e of t he green drum inside the i mag e
drum unit.

Fonts
English
What is a font?
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.
Bitmap fonts are made up of a patter n 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.
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 in the required style, at the full p rinter resolution. Such fonts are therefore said to be scalable and
do not appear ragged at enlarged sizes.
Using fonts
The easiest way to select fonts is through the software
program bein g used. Softw are programs send printer
commands that consist of a set of codes , one for each of
the font characteristi cs. If the software program h a s th e
appropriate driver, fonts can be specified and the n ecessary commands will be sent to the printer. For more detailed information on how to select fonts in a soft ware
program, refer to the documentation for that softw are
program.
