Safety Notices
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 is 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
The printer and its peripherals must be serviced by a customer service representative who has completed
the training course on those models.
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.
• To prevent a fire or explosion, keep the machine away from flammable liquids, gases, and aerosols.
A fire or an explosion might occur.

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.
• 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.
