Performing preventive maintenance NOTE You should replace certain parts when the PERFORM PRINTER MAINTENANCE message appears on the printer control panel display. This will help ensure that your printer maintains optimum performance. The maintenance message will appear every 200,000 pages. The message can be temporarily cleared for approximately 10,000 pages by using the CLEAR MAINTENANCE MESSAGE item on the Resets submenu. (See Resets submenu.) To check the number of pages the printer has printed since new maintenance-kit components were installed, print either a configuration page or a supplies status page. (See Configuration page or Supplies status page for details.) To order the printer maintenance kit, see Part numbers. The kit includes: ● fuser ● rollers (transfer, pickup, and feed) ● installation instructions The printer maintenance kit is a consumable item and is not covered under the original printer warranty or under most extended warranties.
