IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY
1. Be sure that the power cord is unplugged before disassembling or
assembling parts of the copier or peripherals.
2. The wall outlet should be near the copier and easily accessible.
3. Note that electrical voltage is supplied to some components of the copier
and the paper tray unit even while the main power switch is off.
4. If you start a job before the copier completes the warm-up or initializing
period, keep hands away from the mechanical and electrical components
until job execution has started. The copier will start making copies as soon
as warm-up or initialization is finished.
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 nontoxic, but getting either of these into your eyes may
cause temporary eye discomfort. Try to remove with eye drops or flush with
water. If material remains in eye or if discomfort continues, 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 relevant
models.
LITHIUM BATTERIES
Incorrect replacement of lithium battery(s) on the FCU may pose risk of
explosion. Replace only with the same type or with an equivalent type
recommended by the manufacturer. Discard used batteries in accordance with
the manufacturer’s instructi ons.
SAFE AND ECOLOGICAL DISPOSAL
1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly
if exposed to an open flame.
2. Dispose of used toner, developer, and organic photoconductors in
accordance with local regulations. (These are nontoxic 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.
!
WARNING
Use of controls not specified in this manual, or performance of
adjustments or procedures not specified in this manual, may result in
hazardous radiation exposure.
!
WARNING FOR LASER UNIT
WARNING: Turn off the main switch before atte mpting any of the
procedures in the Laser Unit section. Laser beams can cause
serious damage to eyes.
