User’s Guide iii
Safety instructions
English
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 Guide 1
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.
