HP Laserjet Pin Codes

The Laserjet Service Menu is used by printer repair engineers and usually has options like clearing the event log, changing the maintenance count and maintenance interval. Most HP laserjet printer models require a PIN code to access the Service Menu Area. PIN codes for each model can be found in the individual laserjet service manuals, however here is a useful list for quick reference. If you are not a qualified laser printer engineer, please be careful in this area as you are able to overwrite important and critical data. Our engineers often refer to this table when refurbishing printers to ensure that the page counts for the fuser and transfer kits are correct and to help the printer to default to the correct paper size following a cold reset (Power on).
