HP LaserJet 4345 MFP Series Products - How to Perform a Cold Reset
How to perform a cold reset
A cold reset unlocks menus that have been previously locked and resets all control-panel menu items to the factory defaults. A cold reset does not clear the values in the service menu, such as the serial number and the page counts.
NOTE: Before performing a cold reset, print a menu map 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 performing a cold reset. Make note of the IP address that is listed on the Jetdirect configuration page. You will need to restore the IP address after performing a cold reset.
To perform a cold reset:
- Turn the MFP off and then on.
- When the memory count appears on the control-panel display, press and hold 6 until all three LEDs flash once and then stay on. This might take up to 20 seconds.
- Press 3 four times until COLD RESET appears on the control-panel display.
- Press 6 one time. The MFP should continue its initialization sequence.
