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. Note that some components of the copier and the paper tray unit are
supplied with electrical voltage even if the main 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 (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. Never operate the copier without the ozone filters installed.
2. Always replace the ozone filters with the specified ones at the specified
intervals.
3. 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
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.
+ CAUTION
2. The RAM board on the system control board has a lithium battery
which can explode if replaced incorrectly. Replace the battery
only with an identical one. The manufacturer recommends
replacing the entire RAM board. Do not recharge or burn this
battery. Used batteries must be handled in accordance with local
regulations.

SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Do not incinerate the toner bottle or the used toner. Toner dust may
ignite suddenly when exposed to open flame.
2. Dispose of used toner, developer, and organic photoconductor according
to 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.
+ WARNING
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 before attempting any of the
procedures in the Laser Unit section. Laser beams
can seriously damage your eyes.
