Periodic inspection of parts
Periodic replacement parts are the parts that should be inspected and, if required, replaced at
regular intervals. Failure of these parts can seriously affect the printer’s performance. These
parts should be inspected during a regular service visit near the end of their expected life, and
any that are found to be worn or damaged should be replaced.
The following parts should be inspected and, if required, replaced after approximately 150,000
pages of use:
● fuser assembly
● transfer roller
● separation pads (tray 1, tray 2, and tray 3)
● pickup rollers (tray 1, tray 2, and tray 3)
● output feed rollers (upper and lower)
● transport belts and rollers
See "Removal and replacement" in chapter 6 for procedures to remove and replace these parts.
See "Parts and diagrams" in chapter 8 for the part numbers.
Variables such as media, environment, and usage can cause these parts to wear prematurely.
See "Media specifications" in chapter 2 for information about suitable media, environment, and
usage conditions.
