LtIMPORTANTSAFETYNOTICES

PREVENTIONOFPHYSICALINJURY

1. Before disassembling or assembling parts of the copier and peripherals, makesure thatthe copierpower cordis unplugged.

1. The wall outlet should be near the copier and easily accessible.

1. Note that some components ofthe copier and the paper tray unit aresupplied with electrical voltage even if the main power switch is turned off.

1. If any adjustment or operation check has to be made with exterior covers offor open while the main switch is turned on, keep hands away from electrified or mechanically driven components.

1. If the Start key is pressed before the copier completes the warm-up period(the Start key starts blinking red and green alternatively), keep hands awayfrom the mechanical and the electrical components as the copier startsmaking copies as soon as the warm-up period is completed.

1. The inside and the metal parts of the fusing unit become extremely hot while the copier is operating. Be carefulto avoid touching those components with your bare hands.

HEALTHSAFETYCONDITIONS

1. Never operate the copier without the ozone filters installed.

1. Always replace the ozone filters with the specified ones at the specified intervals.

1. Tonerand developer are non-toxic, but if you geteither of them in your eyes by accident, it may cause temporary eye discomfort. Try to remove with eyedrops or flush with water as first aid.If unsuccessful, get medical attention.

OBSERVANCEOFELECTRICALSAFETYSTANDARDS

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.

1. The NVRAM on the system control board hasa lithium battery which can explode if replaced incorrectly. Replace the NVRAM onlywith an identical one. The manufacturer recommends replacing the entire NVRAM. Do not recharge orburn this battery. Used NVRAM must be handled in accordancewith local regulations.

SAFETYANDECOLOGICALNOTESFORDISPOSAL

1. Do not incinerate toner bottles orused toner. Toner dust may ignite suddenly when exposed to an open flame.

1. Dispose of used toner, developer, and organic photoconductors in accordance with local regulations. (These are non-toxic supplies.)

1. Dispose of replaced parts in accordance with local regulations.

1. 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.

LASERSAFETY

The Center for Devices and Radiological Health (CDRH) prohibits the repair oflaser-based optical units in the field. The optical housing unit can only be repaired ina factory or ata location with the requisite equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer. The laser chassis is not repairablein the field. Customer engineersare therefore directed to return all chassis and laser subsystems tothe factory or service depot when replacement ofthe optical subsystem is required.
