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.

• 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

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.
