Service mode functions
Service menu
Use the control-panel Service menu to troubleshoot device problems.
Service menu settings
The Service menu is used to calibrate, restore factory default settings, and clean the print paper path. The following Service menu items are available:
# Restore defaults - used to reset all customer-accessible menu settings back to the factory default settings (except language) using the control panel or software
NOTE: This service menu item does not reset factory-settable settings, including formatter number, page counts, factory paper settings, language, and so on.
# PowerSave - used to configure the amount of idle time before the engine enters sleep mode
# Cleaning mode - used to remove dust and toner from the print paper path
Restore the factory-set defaults
1. Press OK to open the menus.
2. Use the Left arrow or the Right arrow button to select Service, and then press OK.
3. Use the Left arrow or the Right arrow button to select Restore defaults, and then press
The product automatically restarts.

Secondary service menu
Use the secondary service menu to print service-related reports and to run special tests. Customers do not have access to this menu.
Open the secondary service menu
1. Ensure the product is in the Ready state.
2. Press OK to open the menus.
3. Simultaneously press Left arrow and OK to open the secondary service menu.
4. Press the Left arrow and the Right arrow to navigate through the menu.

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 HP ToolboxFX or the Service menu. A cold reset 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.
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.
Perform an NVRAM initialization
1. Turn the product off.
2. Simultaneously press the Right arrow button and the X button. Keep these buttons depressed as you turn the product on.
3. When Permanent storage init. appears on the display, release both buttons.
4. When the product has finished the NVRAM initialization, it returns to the Ready state.
