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:
• 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
the edge.
• If you must open the printer’s upper door for more than three minutes,
remove the print unit with the toner cartridge 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.
• Replace the toner cartridge as soon as possible to prevent any dust from
entering the print unit from the opening.
• Shake the toner cartridge before installation.
