Safety Notices
Important Safety Notices
Prevention of Physical Injury
1. Before disassembling or assembling parts of the machine and peripherals, make sure that the
machine power cord is unplugged.
2. The wall outlet should be near the machine 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 machine 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 machine
starts operation.
5. The inside and the metal parts of the fusing unit become extremely hot while the machine 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 machine 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.
The Controller board on the MF model contains a lithium battery. 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 batteries in accordance with
the manufacturer's instructions and local regulations.
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:
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.
