HP LaserJets - Cold Reset Instructions
Cold resetting a printer resets the
printer to factory defaults.
Please note: Any settings you make at the printers
control panel will be reset to factory defaults, including the IP
address if you have a JetDirect card installed.
Remove the JetDirect
card while you cold reset the printer if you don't want to erase
the JetDirect card's settings.
You can also reset the NVRAM. Resetting the NVRAM will clear the
page count and reset the service mode settings to factory defaults.
On printers with a display panel you need to enter service mode
to manually change the information stored in NVRAM. On printers
that don't have a display panel, such as a 5P, 6P, 2100, 2200 there
is a different procedure outlined below.
"Older" printers with a display panel. (e.g. 4000, 4100, 5si, 8000,
etc.)
Cold resetting the printer is simply a matter of turning the power
off, holding down the GO or Online button while turning the printer
on.
Resetting NVRAM settings must be done manually through service mode.
See
entering service mode.
"Newer" printers with a display panel. (e.g. 2300, 2400, 4200, 4250/4350, 4300, etc.)
Turn the printer off and then on. When the printer begins its memory
count, press and hold down the Checkmark button until all the main LED
signal lights illuminate and stay illuminated. Then release the
Checkmark button, and use the Up/Down arrow keys to find the Cold Reset
option, then press the Checkmark button again to choose that option.
Printers with no display panel.
HP 1100, 1200 - While the printer is on, press
and hold the Go button for 5 seconds. This will reset the printer.
To reset the NVRAM. Turn the printer off. Press and hold the Go
button for 20 seconds while powering on the printer.
HP 2100 - To perform a cold reset, turn the printer
power off, then press and hold the JOB CANCEL button. Turn the printer
power back on and after all the LEDs come on release the JOB CANCEL
button. A cold reset changes most system parameters in NVRAM to
the factory defaults. The JOB CANCEL button must be released within
20 seconds after all of the LEDs come on; otherwise, an NVRAM initialization
is performed instead of a cold reset.
