Safety Notices
Important Safety Notices
Prevention of Physical Injury
1.Before disassembling or assembling parts of the printer and peripherals, make sure that the printer power cord is unplugged.
2.The wall outlet should be near the printer and easily accessible.
3.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.
4.The printer drives some of its components when it completes the warm-up period. Be careful to keep hands away from the mechanical and electrical components as the printer starts operation.
5.The inside and the metal parts of the fusing unit become extremely hot while the printer is operating. Be careful to avoid touching those components with your bare hands.
Health Safety Conditions
Toner and developer are non-toxic, but if you get either of them in your eyes by accident, it may cause temporary eye discomfort. Immediately wash eyes with plenty of water. If unsuccessful, get medical attention.
Observance of Electrical Safety Standards
The printer and its peripherals must be serviced by a customer service representative who has completed the training course on those models.
Lithium Batteries
Incorrect replacement of lithium battery(s) on the EGB and controller board 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.

Safety and Ecological Notes for Disposal
1.Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when exposed to an open flame.
2.Dispose of used toner, the maintenance unit which includes developer or the organic photoconductor in accordance with 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.
Use of controls, or adjustment, or performance of procedures other than those specified in this manual may result in hazardous radiation exposure.
Turn off the main switch before attempting any of the procedures in the Laser Optics Housing Unit section. Laser beams can seriously damage your eyes.
