IMPORTANT SAFETY NOTICES
REVENTION 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. 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.
4. If a job has started before the copier completes the warm-up or initializing
period, keep hands away from the mechanical and electrical components
because the starts making copies as soon as the warm-up period is
completed.
5. 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.
6. Keep the machine away from flammable liquids, gases, and aerosols. A fire
or an explosion might occur.
HEALTH SAFETY CONDITIONS
Toner is non-toxic, but if you get it 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.
SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Do not incinerate the toner cassettes. Toner dust may ignite suddenly when
exposed to an open flame.
2. Dispose of toner cassettes in accordance with local regulations. (This is a
non-toxic unit.)
3. Dispose of replaced parts in accordance with local regulations.
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 NVRAM on the Controller board has a lithium battery which can explode
if replaced incorrectly. Replace the NVRAM only with an identical one. Do
not recharge or burn this battery. Used NVRAM must be handled in
accordance with local regulations.
3. The danger of explosion exists if batteries on the FCU, MBU and JBIG are
incorrectly replaced. Replace only with the same or an equivalent type
recommended by the manufacturer. Discard used batteries in accordance
with the manufacturer’s instructions.

LASER SAFETY
The Center for Devices and Radiological Health (CDRH) prohibits the repair of
laser-based optical units in the field. The optical housing unit can only be repaired
in a factory or at a location with the requisite equipment. The laser subsystem is
replaceable in the field by a qualified Customer Engineer. The laser chassis is not
repairable in the field. Customer engineers are therefore directed to return all
chassis and laser subsystems to the factory or service depot when replacement of
the optical subsystem is required.
WARNING
Use of controls, or adjustment, or performance of procedures other than
those specified in this manual may result in hazardous radiation exposure.
WARNING FOR LASER UNIT
WARNING: Turn off the main switch before attempting any of the
procedures in the Laser Unit section. Laser beams can
seriously damage your eyes.
CAUTION MARKING:
LASER-4.WMF
Safety Precautions for This Machine
Before moving the mainframe:
•Disconnect all peripheral units (finisher, LCT, etc.) from the mainframe.
•Pull the slide handles out of the mainframe and use them to lift the mainframe.
