!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 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.

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 attempting any of the procedures in the Laser Unit section. Laser beams can cause serious damage to eyes.
