This chapter covers preventive maintenance, periodic routine
maintenance, and repacking the printer for shipment or storage.

Before performing any maintenance, be sure that the printer is turned
off.

During maintenance procedures, do not touch any connector contacts
to avoid possible electrostatic damage to the printer.

When performing maintenance, do not disassemble or remove any
components unless specifically directed in the procedures.

The following guidelines can help to ensure trouble-free operation:
• Follow the guidelines in Chapter 1 when selecting a location for your

printer.

• To minimize paper jams, store paper under favorable conditions. Do

not expose paper to high humidity or moisture, which can cause
wavy edges. Do not store paper in direct sunlight or allow it to
become very dry, which can impart an electrostatic charge. Store
paper flat, not on edge.

• If you must open the printer’s upper door for more than three

minutes and remove the print unit (developer unit and drum unit),
close the shutter of the drum unit or store the print unit in a dark,
clean, level place. Exposure of the photoconductor drum to dust or
light can cause damage. 

• Make sure small objects such as paper clips do not drop into the

printer.

• When the message display indicates 

REPLACE PARTS

, print a status

report or display a 

<CLEAR WARNING>

 message in menu mode to

confirm the cause of the message. For the procedures, see Chapter 2.

• Shake the print unit before installation.
