IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the printer and peripherals,
make sure that the printer power cord is unplugged.
2. The wall outlet should be near the printer and easily accessible.
3. Note that some components of the printer and the paper tray unit are
supplied with electrical voltage even if the main power 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. The inside and the metal parts of the fusing unit become extremely hot while
the printer is operating. Be careful to avoid touching those components with
your bare hands.
HEALTH SAFETY CONDITIONS
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 printer 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 system control board has a lithium battery which can
explode if replaced incorrectly. Replace the NVRAM only with an identical
one. The manufacturer recommends replacing the entire NVRAM. Do not
recharge or burn this battery. Used NVRAM must be handled in accordance
with local regulations.
SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly
when exposed to an open flame.
2. Dispose of used toner, developer, and organic photoconductors in
accordance with local regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.
4. When keeping used lithium batteries in or der 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.
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
WARNING: Turn off the main switch before atte mpting any of the
procedures in the Laser Unit section. Laser beams can seriously damage
your eyes.

Lithium Batteries (Memory Back-up)
!
CAUTION
The danger of explosion exists if a battery of this type is 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.
