Performing preventive maintenance
You should replace certain parts when the PERFORM PRINTER MAINTENANCE message

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.)
