HP LaserJets Cold Reset Instructions

Cold resetting a printer resets the printer to factory defaults. Please note: Any settings you make at the printers control panel will be reset to factory defaults, including the IP address if you have a JetDirect card installed. Remove the JetDirect card while you cold reset the printer if you dont want to erase the JetDirect cards settings.

You can also reset the NVRAM. Resetting the NVRAM will clear the page count and reset the service mode settings to factory defaults. On printers with a display panel you need to enter service mode to manually change the information stored in NVRAM. On printers that dont have a display panel, such as a 5P, 6P, 2100, 2200 there is a different procedure outlined below.

"Older" printers with a display panel. (e.g. 4000, 4100, 5si, 8000, etc.)

Cold resetting the printer is simply a matter of turning the power off, holding down the GO or Online button while turning the printer on.

Resetting NVRAM settings must be done manually through service mode. See entering service mode.

"Newer" printers with a display panel. (e.g. 2300, 2400, 4200, 4250/4350, 4300, etc.)

Turn the printer off and then on. When the printer begins its memory count, press and hold down the Checkmark button until all the main LED signal lights illuminate and stay illuminated. Then release the Checkmark button, and use the Up/Down arrow keys to find the Cold Reset option, then press the Checkmark button again to choose that option.

Printers with no display panel.

HP 1100, 1200 - While the printer is on, press and hold the Go button for 5 seconds. This will reset the printer. To reset the NVRAM. Turn the printer off. Press and hold the Go button for 20 seconds while powering on the printer.

HP 2100 - To perform a cold reset, turn the printer power off, then press and hold the JOB CANCEL button. Turn the printer power back on and after all the LEDs come on release the JOB CANCEL button. A cold reset changes most system parameters in NVRAM to the factory defaults. The JOB CANCEL button must be released within 20 seconds after all of the LEDs come on; otherwise, an NVRAM initialization is performed instead of a cold reset.

Instructions How to Reset Ink Counter Using Adjustment Program

Since your printer consumes ink not only for printing but also for other operations like cleaning, a certain amount of ink is wasted and it is collected by the waste ink pad. Therefore, the printer counts the amount of waste ink.
Once the amount of waste ink reaches the predefined limit, the printer indicates "MAINTENANCE REQUEST" and the waste ink pad should be replaced. Also, you must reset the maintenance error condition and the waste ink counter value stored in EEPROM on the mainbord of the printer.

The adjustment program enables you to perform maintenance and adjustment functions such as:
* EEPROM initial setting
