HP LaserJet - Maintenance Count Reset
If the display panel on your HP laserjet reads "perform printer maintenance", "perform user maintenance", or anything smilar, then you need to order a maintenance kit. This normally includes a fuser and various rollers that need replacing on a regular basis. The printer will display this message after a certain number of pages have been printed, ie on the LaserJet 4000 it will appear every 200,000 pages. To clear the message you need to reset the maintenance count, which can be done as follows -
Reset the maintenance count on an HP Laserjet 8000, 8100, and 8150
After installing a maintenance kit, reset the maintenance count to zero by:
1. Enter service mode (see Entering Service Mode page)
NOTE: Do not change the MAINTENANCE INTERVAL value, which is another option in service mode. This value is the interval at which a maintenance kit should be installed (350,000 pages on Laserjet 8000, 8100, or 8150 series).

After you install the maintenance kit, you can clear the PERFORM USER MAINTENANCE message by going to the printers control panel Configuration Menu and setting the SERVICE MESSAGE = to OFF. Note: this message will only appear in the Configuration Menu if the PERFORM USER MAINTENANCE message appears.
