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.
The Controller board on this machine 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.
The optional fax and memory expansion units contain lithium batteries, which can explode
if replaced incorrectly. Replace only with the same or an equivalent type recommended by
the manufacturer. Do not recharge or burn the batteries. Used batteries 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, 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.
Lithium Batteries
Incorrect replacement of lithium battery(s) on the FCU, controller board and memory board unit
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
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.
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.
