Cold reset
The traditional cold reset function found in other HP LaserJet products is not supported for this
product. The equivalent function is the Restore defaults option in the Service menu.
Restoring the default settings unlocks menus that have been previously locked and resets all control-
panel menu items to the factory defaults. It does not reset the serial number and the page counts.
NOTE: Before restoring defaults, print a menu structure report and a configuration page. Use the
information on these pages to reset customer-specific settings.
CAUTION: All HP Jetdirect 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 Jetdirect configuration page. You
might need to restore the IP address after restoring defaults.
NVRAM initialization
CAUTION: All HP Jetdirect settings are also reset. Be sure to print a configuration page before
performing an NVRAM initialization. Make note of the IP address that is listed on the Jetdirect
configuration page. You need to restore the IP address after performing an 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.
After performing an NVRAM initialization, reconfigure any computers that print to this product so that
the computers can recognize the product.
