How to perform a Cold Reset on HP LaserJet 4300

Performing a cold reset will reset all control‐panel menu items back to the factory defaults. It will also reset all HP Jetdirect card settings such as IP address and method of configuration. As a good general practice you should always print out the configuration page before performing the cold reset. The configuration page contains all Jetdirect card settings. A cold reset does NOT clear the values in the service menu, such as the serial number and page counts.

To Perform a Cold Reset via Control Panel:


  1. Turn the printer off...wait few seconds
  2. Hold down (SELECT button), and then turn the printer power on.
  3. Continue holding down key until all three LED lights remain lit. (Note: The LED’s will flash initially. Do not release the key until all LED’s are solidly lit. This might take up to 10 seconds)
  4. Release key
  5. When the message Select Language appears on the display, use (UP ARROW button) or (DOWN ARROW button) to scroll through the options
  6. When Cold Reset is displayed, Press Key to select it.
  7. If a bootloader password has been set, a prompt to enter the password will be displayed in the control panel. Input the bootloader password and press the Key to confirm the entry.
  8. The printer should continue its boot sequence.

Note: A printer boot sequence is complete when READY appears on the control-panel.
