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. 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. The printer drives some of its components when it completes the warm-up
period. Be careful to keep hands away from the mechanical and electrical
components as the printer starts operation.
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. Immediately wash eyes with
plenty of water. If unsuccessful, get medical attention.
OBSERVANCE OF ELECTRICAL SAFETY STANDARDS
The printer and its peripherals must be serviced by a customer service
representative who has completed the training course on those models.
LITHIUM BATTERIES
Incorrect replacement of lithium battery(s) on the EGB may pose risk of
explosion. Replace only with the same type or with an equivalent type
recommended by the manufacturer. Discard used batteries in accordance with
the manufacturerÓs instructions.
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, the maintenance unit which includes developer or the
organic photoconductor 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 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.
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 attempting any of the
procedures in the Laser Optics Housing Unit section. Laser
beams can seriously damage your eyes.
