1IMPORTANT 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. 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 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.
5. If the "Start" key is pressed before the copier completes the warm-up period
(the "Start" key starts blinking red and green alternatively), keep hands away
from the mechanical and the electrical components as the copier starts
making copies as soon as the warm-up period is completed.
6. 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. Always replace the ozone filters with the specified ones at the specified
intervals.
2. Toner is non-toxic, but if you get it 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
1. The copier and its peripherals must be installed and maintained by a
customer service representative who has completed the training course on
those models.
2. The danger of explosion exists if batteries on the FCU and JBIG are
incorrectly replaced. Replace only with the same or an equivalent type
recommended by the manufacturer. Discard used batteries in accordance
with the manufacturer's instructions.
SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Do not incinerate AIO cartridge. Toner dust may ignite suddenly when
exposed to and open flame.
2. Dispose of used AIO cartridge in accordance with local regulations. (This is
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.

1WARNING
Use of controls, or adjustment, or performance of procedures other than
those specified in this manual may result in hazardous radiation exposure.

1WARNING FOR LASER UNIT
WARNING: Turn off the main switch before attempting any of the
procedures in the Laser Unit section. Laser beams can
seriously damage your eyes.
