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.
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.

Page 4
• 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.

(Average Copy Volume) for this product, these "yield parts*1 " are expected to outlast the working
life of the machine.
*1 "Yield Parts": Parts whose expected yield is longer than the machine lifetime when taking into
consideration the machine's ACV.
Description Expected Yield Q'ty/unit
Paper Feed Roller 120 K prints 1
Transfer Roller 120 K prints 1
Fusing Unit 120 K prints 1
Yield Counter
Yield counters for each yield part can be checked by the following methods.
