Laserjets 5P, 6P, 2100, 2200 and other printers that
do not have a display panel (LEDs only).
These models are designed as low volume personal printers and do
not have a maintenance count that needs to be reset or a readily
accessible service mode. You can cold reset these printers or completely
reinitialize the NVRAM (nonvolatile ram) to factory defaults. Cold
resetting will reset most of the system parameters to factory defaults
and reinitializing the NVRAM will reset ALL system parameters to
the factory defaults. Also, there is a service mode for these printers
but it is only accessible through software using PJL service mode
commands. Buy the printer's service manual if you want to learn
more.
HP Laserjet 5L, 6L, 1100, 1200 do not have a service mode. You can
only perform a cold-reset and continuous self-test.
Multifunction printers - printers/copiers/fax/scanners (e.g.
HP 3100, 3150, 3200, etc.)
Service modes in these printers are more extensive because of the
scanning and faxing features. We recommend buying the service manual
for these units if you will be doing any repairs beyond mechanical
components.
