From the manual

NVRAM initialization
CAUTION Initializing the NVRAM resets the serial number, the event log, the page counts, and
the EIO card (initializing the NVRAM resets SERVICEmenu values to factory defaults). Use the
service menu to restore the serial number and page counts. Also reconfigure any computers that
print to this device so that the computers can recognize the device. Initialize the NVRAM only
when absolutely necessary. In most situations, use a cold reset rather than a NVRAM initialization
to reset device settings (this will retain the values in the SERVICEmenu).
NOTE Before performing a NVRAM initialization, print a menu map and a configuration page
. Use the information on the configuration page to reset
any customer-set device configuration values that the NVRAM initialization procedure changes.
Take special note of the total page count, maintenance count, and the serial number.
1. Remove any installed accessories.
2. Turn the device off.
3. Turn the device on. When the memory count begins, press and hold the button. Continue
holding down the button until all three device control-panel lights flash once and then remain
on. This might take up to 10 seconds.
4. Press the button.
5. Press the Menubutton. The display should show SKIP DISK LOAD.
6. Press the button until NVRAM INITis highlighted.
7. Press . The device initializes NVRAM and then continues the power-on sequ

If nothing else works, you may have to manually calibrate the dials inside the mirror box. This video link will show you how. http://youtu.be/R1DIko0a1MA
This may be necessary if the printer got bumped really hard.

NVRAM initialization
CAUTION NVRAM initialization will erase all network settings. Before performing NVRAM
initialization, print a Network Configuration page, which contains network-setting information.
NVRAM initialization performs the following actions:
? Resets all customer-accessible menu settings via control panel and software back to the factory
default settings
? Resets the language to the value set at the factory
? Resets the default media size to cold reset media size
? Resets the symbol set to PC-8
NOTE The following steps reset the same NVRAM locations that are reset using the
Restore Defaults option in the control panel Service menu. The following process should be
used if the MFP does not come to a Ready state and an NVRAM initialization is desired.
Use the following procedure to perform an NVRAM initialization.
1. Turn off the printer.
2. Press and hold the Right arrow and Cancel buttons simultaneously.
3. Turn on the printer.
4. When you see the message Permanent storage init, release the Right arrow and Cancel buttons.
When the NVRAM init is complete, the printer returns to the Ready state.

Cold reset
A cold reset changes most system parameters in NVRAM to the factory defaults. However, unlike NVRAM inititialization, a cold reset does not reset the page count, the paper tray sizes, language, or formatter number.
Note If an HP Jetdirect card is installed, remove it before performing a cold reset. Otherwise, the procedure will also reset all the HP Jetdirect settings as well as the printer settings.
To perform a cold reset
1 Turn the printer off.
2 Press and hold down the GO button.
3 Turn the printer on, and continue to hold the GO button for at least 5 seconds, but not longer than 15 seconds. During this process, the Attention LED will turn on.
4 Release the GO button.
Note If both the Attention and the Ready LEDs turn on before you release the GO button, you must start the procedure again with step 1.
5 The printer's LEDs will begin cycling. The cold-reset process will
run until completion, and the printer will return to the ready state.

NVRAM initialization

CAUTION Only perform the following procedure if absolutely necessary.
Performing an NVRAM initialization resets some parameters that cannot be restored later.
NVRAM initialization sets all default variables stored in NVRAM back to factory default values or to a default ROM value, depending on the variable. It also performs a system reset.

NVRAM initialization resets the following:

• all menu settings to factory default values

• factory settings such as formatter number, page counts, and factory paper settings
  

To perform NVRAM initialization
1 Turn the printer off.
2 Press and hold down the GO button.
3 Turn the printer on, and continue to hold the GO button for at least 20 seconds. During this process, the GO button, Attention, and Ready LEDs will each turn on.
4 Release the GO button.
5 The printer LEDs will begin cycling. The NVRAM-unit process will run until the printer is in the ready state.

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.
HP 2200 -
Cold reset:
1. Turn the printer power off.
2. Press and hold GO.
3. Turn the printer power back on and continue to hold GO until the Attention light turns on.
4. Release GO.
5. The device lights will begin cycling from front to rear. The cold-reset process will run until completion and the device will go to the ready state.

NVRAM Reset:
1. Turn the printer power off.
2. Press and hold GO.
3. Turn the printer power back on and continue to hold GO until the Attention, Ready, and Go lights turn on.
4. Release GO.
5. The device lights will begin cycling from font to rear. The NVRAM initialization will run until completion and the device will go to the ready state.
HP 5P & 6P
Cold reset:
Turn the power off and hold the reset button (button closest to the back of the printer) for LESS than 20 seconds while turning the printer on.
Reset the NVRAM:
Turn the power off and hold the reset button for MORE than 20 seconds while turning the printer on..
