SERVICE MANUAL
IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the copier and peripherals,
make sure that the copier power cord is unplugged.
2. The wall outlet should be near the copier and easily accessible.
3. Note that some components of the copier and the paper tray unit are
supplied with electrical voltage even if the main switch is turned off.
4. If any adjustment or operation check has to be made with exterior covers
off or open while the main switch is turned on, keep hands away from
electrified or mechanically driven components.
5. If the hot roller temperature is low when the main switch is turned on, the
copier starts idling automatically when the warm-up period is completed.
Keep hands away from the mechanical and the electrical components to
avoid any injury.
6. If the start key is pressed before the copier completes the warm-up period
(Ready indicator starts blinking), keep hands away from the mechanical
and the electrical components as the copier starts making copies as soon
as the warm-up period is completed.
7. The inside and the metal parts of the fusing unit become extremely hot
while the copier is operating. Be careful to avoid touching those
components with your bare hands.
HEALTH SAFETY CONDITIONS
1. Never operate the copier without the ozone filters installed.
2. Always replace the ozone filters with the specified ones at the specified
intervals.
3. Toner and developer are non-toxic, but if you get either of them in your
eyes by accident, it may cause temporary eye discomfort. Try to remove
with eye drops or flush with water as first aid. If unsuccessful, get medical
attention.
OBSERVANCE OF ELECTRICAL SAFETY STANDARDS
1. The copier and its peripherals must be installed and maintained by a
customer service representative who has completed the training course
on those models.
2. The RAM board on the main control board has a lithium battery which can
explode if replaced incorrectly. Replace the battery only with an identical
one. The manufacturer recommends replacing the entire RAM board. Do
not recharge or burn this battery. Used batteries must be handled in
accordance with local regulations.
SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Do not incinerate the toner cartridge or the used toner. Toner dust may
ignite suddenly when exposed to open flame.
2. Dispose of used toner, developer, and organic photoconductor according
to local regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.
4. When keeping used lithium batteries in order to dispose of them later, do
not put more than 100 batteries per sealed box. Storing larger numbers or
not sealing them apart may lead to chemical reactions and heat build-up.
