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.
