Performing preventative maintenance
You should replace certain parts when the PERFORM PRINTER MAINTENANCE message appears
on the printer control-panel display. This helps your printer maintain optimum performance.
The maintenance message appears every 200,000 pages. The message can be temporarily
cleared for approximately 10,000 pages using the CLEAR MAINTENANCE MESSAGE item on the
Resets submenu. (See Control-panel menus on page 247.) To check the number of pages that
the printer has printed since new maintenance-kit components were installed, print either a
configuration page (see Configuration page on page 241) or a supplies status page (see
Supplies status page on page 242).
To order the printer maintenance kit, see chapter 8. The kit includes the following components:
