Safety Notices
Important Safety Notices
Prevention of Physical Injury
1. Before disassembling or assembling parts of the copier and peripherals, make sure that the
power cord is unplugged.
2. The wall outlet should be near the copier and easily accessible.
3. Note that some components of the copier and the paper tray unit are supplied with electrical
voltage even if the main power switch is turned off.
4. If a job has started before the copier completes the warm-up or initializing period, keep hands
away from the mechanical and electrical components because the starts making copies as
soon as the warm-up period is completed.
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
Toner and developer are 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 copier and its peripherals must be installed and maintained 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, developer, and organic photoconductors in accordance with local
regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with 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 FOR LASER UNIT
WARNING: Turn off the main switch bef
ore attempting any of the procedures in the
Laser Unit section. Laser beams can seriously damage your eyes.
