Safety Notices
Important Safety Notices
Prevention of Physical Injury
1. Before disassembling or assembling parts of the copier and peripherals, make sure
that the copier power cord is unplugged.
2. The wall outlet should be near the copier 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 copier 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
copier starts operation.
5. The inside and the metal parts of the fusing unit become extremely hot while the copier
is operating. Be careful to avoid touching those components with your bare hands.
Health Safety Conditions
1. 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.
2. The copier, which use high voltage power source, can generate ozone gas. High
ozone density is harmful to human health. Therefore, the machine must be installed in
a well-ventilated room.
Observance of Electrical Safety Standards
The copier and its peripherals must be serviced by a customer service representative who
has completed the training course on those models.
Keep the machine away from flammable liquids, gases, and aerosols. A fire or
an explosion might occur.
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.
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.
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.
