Performing Routine Maintenance
Hewlett-Packard recommends that only HP-authorized service
technicians service the printer. However, you should replace certain
parts when the

message appears
on the printer’s control panel display.
The maintenance message will appear every 200,000 pages. To
check the number of pages the printer has printed, print a
configuration page (see page 134).
To order the printer maintenance kit, see page 9. The kit includes:
fuser assembly
transfer roller
feed rollers
necessary instructions
Note The printer maintenance kit is a consumable and is not covered
under warranty.
