Preventive 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
•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 status report or display a <CLEAR WARNING> message in menu mode to confirm the cause of the message. For the procedures, see Chapter 2.
•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.
