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.

• 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.
