CHAPTER
Maintenance
This chapter covers preventive maintenance, periodic routine
maintenance, and repacking the printer for shipment or storage.
Notice:
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, remove the print unit with the toner bottle mounted and
store it in a dark place. Exposure of the photoconductor drum to
light for more than three minutes 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 3.
• Replace the toner bottle as soon as possible to prevent any dust
from entering the print unit from the opening.
• Shake the toner bottle before installation.
