Handing the photoconductor unit

The following precautions must be observed when handling the photoconductor unit. The photoconductor unit is
a supply item you will have to remove during some of the repair procedures:

Transportation/storage

Use the specified carton whenever moving or storing the photoconductor unit.

Handling

•

The optical photoconductor roller in the photoconductor unit exhibits the greatest light fatigue after being
exposed to strong light over an extended period of time. Never expose it to direct sunlight. Cover the
photoconductor unit when you remove it from the printer.

•

Use care not to contaminate the surface of the optical photoconductor roller with an oil-based solvent,
fingerprints, and other foreign matter.

•

Do not scratch the surface of the optical photoconductor roller.

Parts not to be touched

Any part where the mounting screws are used to meet a printer alignment set at the factory must not be
removed, disassembled, or adjusted.
