HP LaserJet 4250 and 4350 Series Printers - Performing a Cold Reset

NOTE: The Jetdirect LAN (such as the IP address of the printer) settings will be reset to defaults by this operation. Record LAN settings before resetting the printer. Reconfigure LAN settings after the reset if you are using a LAN connection).

To avoid resetting the LAN settings disable the embedded Jetdirect before performing a Cold Reset by choosing the Disable LAN option from the choices available when you get to step 5 below. Note that after choosing to disable the LAN it is necessary to reboot the printer and then choose to perform the Cold Reset. During the power up sequence only one operation can be performed at a time. In this case, first disable the LAN, then reboot the printer and perform the Cold Reset followed by another reboot to reenable the LAN.

To perform a cold reset:

  1. Turn the printer power off.

  2. Power on the printer and watch for the memory count to begin.

  3. Hold down the SELECT (Checkmark) button, when you see the memory count begin.

  4. Continue holding down the SELECT (Checkmark) button until all three printer control-panel lights flash once and then remain on. This might take up to 10 seconds.

  5. After the message SELECT LANGUAGE appears on the display, press the UP ARROW button or the DOWN ARROW button until COLD RESET appears on the display

  6. Press the SELECT (Checkmark) button. The printer performs a cold reset and then continues its power-on sequence.

  7. Check all I/O settings and reset any user-set printer configuration values. 
    NOTE: Before the I/O (LAN) settings can be reset to their correct values the embedded Jetdirect must first be renabled to make those options visible and available on the control panel of the printer. Renable it in the control panel settings then reset them to their correct values.
