HP LaserJet 9000 MFP Series Printer Resets
Cold reset clears all data from the printer memory and sets all the defaults back to the factory
CAUTION Performing a cold reset resets the Jetdirect configuration. To avoid making changes to your network
configuration, remove the HP Jetdirect print server before performing a cold reset.
Note If possible, print a configuration page and menu map prior to performing a cold reset. This will document
current settings for later reference.

To initialize NVRAM
NVRAM initialization resets all the defaults back to the factory settings. NVRAM initialization should
always be executed immediately after replacing the firmware or the formatter board. This procedure
aligns the firmware with the formatter. Not performing NVRAM initialization could result in
deterioration of print quality.

will document current settings for later reference.
