HP Pro 4300 C9H70UT C9H70UT#ABA manual Performing preventative maintenance

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:

●fuser
