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 -

After installing a maintenance kit, reset the maintenance count to zero by:

1. Enter service mode (see Entering Service Mode page)
2. Go to the MAINTCOUNT screen and press + or - to scroll the number to zero (all zeros).
3. Press the Select button to enter the settings into the printers memory (an asterisk will appear next to the zeros).
4. Exit service mode by pressing the GO button.

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).
