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 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 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.
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
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 Elect rical Safety St an dards
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.
Keep the machine away from flammable liquids, gases, and aerosols. A fire or an
explosion might occur if this precaution is not observed.
Lithium Batteries
Incorrect replacement of lithium battery(s) on the FCU, controller board and memory board unit
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
instructions.
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.
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.
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.
Do not use the cleaner to suck spilled toner (including used toner). Sucked toner may
cause firing or explosion due to electrical contact flickering inside the cleaner. However, it
is possible to use the cleaner designed for dust explosion-proof purpose. If toner is
spilled over the floor, sweep up spilled toner slowly and clean remainder with wet cloth.
WARNING FOR LASER UNIT
Turn off the main switch before attempting any of the procedures in the Laser
Unit section. Laser beams can seriously damage your eyes.
