NVRAM initialization

Performing an NVRAM initialization resets the following settings and information:

• All menu settings are reset to factory default values.
• All localization settings, including language and country/region, are reset.

CAUTION:
All onboard network settings are also reset. Be sure to print a configuration page before restoring defaults. Make note of the IP address that is listed on the configuration page. You might need to restore the IP address after an NVRAM initialization.

After performing an NVRAM initialization, reconfigure any computers that print to this printer. Uninstall and then reinstall the product software on the computers.

Super NVRAM initialization

WARNING!
A super NVRAM initialization resets the printer page count and removes the formatter association to the printer serial number. The lack of formatter association to the printer serial number might affect the printer's warranty entitlement. Also, the printer will not be allowed to connect to the HP cloud.

A super NVRAM initialization restores the printer to the “generic printer mode” in which it arrived from the factory. This means that you will have to reset the language and country/region settings when the printer starts after the initialization. A super NVRAM initialization erases all data stored in the protected and unprotected NVRAM sections.

1. Turn the printer off.
2. LED control panels:
   Press and hold down the Resume/Cancel button for about 60 seconds until the green LED illuminates.

   Press and hold the left-arrow button and the Cancel button simultaneously. Keep the buttons depressed as you turn the printer on.
   Touchscreen control panels:
   Turn the printer on, and then, as soon as the HP logo appears, press the lower left quadrant of the control panel.

   The super NVRAM initialization starts.
