Reset a Lexmark Multi Function Printer

We accidentally set a bad password on a Lexmark X422 and I couldn't find the procedure to reset it anywhere. I contacted Lexmark support and they sent me the steps to get into the configuration menu where you can reset the printer back to factory defaults.
  1. Press and hold the Start and Stop buttons and turn on the printer.
  2. Hold the buttons down until “Performing Self Test” is displayed on the LCD.
  3. Release the buttons and “Configuration Menu” is displayed.
  4. Scroll to the RESTORE FACTORY DEFAULTS item on the menu and press select.
  5. Now scroll to RESTORE BASE and press select this sould reset your network card password. There is also a RESTORE NETWORK, this will erase the network configuration but will not reset the password.
I don't know how many other printers this will work on but I'm betting most of the all in one printers from Lexmark will work the same.


  • This seems a good place to add information for a different model :) I have the X342n and I used the built-in web server to restrict the list of allowed IPs (since the printer had a static IP). After which I moved to another apartment and my IPs changed. So then I could no longer print nor access the web based configurator to change the restricted IPs. Very smart, I know.

    So I called Lexmark support and here's how to reset the X342n to factory defaults: After powering up the printer, press Menu, * key, # key (do not hold them, just press and release). You should see a secret menu, the first option being "Serial number". From there, I scrolled down to Network menu -> NVRAM reset to reset the network card. There also seems to be a Utilities menu which allows a full system reset.

    My 2 cents.

  • The same procedure (start and stop keys) seems to work for a Lexmark 9500

  • In case anyone's looking, your instructions also work for the IBM Infoprint 1410 MFP Multi-function printer.

    Thanks for the help! :)

  • does anyone know how to reset a forgotten password on a lexmark X543? Thanks

  • Doesn't work for the X4550. In this printer you should press "Color Start" and "Settings" buttons instead, and then turn on the power hoding them pressed. Maybe it'll work for the X543 and X560n mentioned in previous posts.

  • The Lexmark 466 models, use the keys 2 and 6. Both need to be held down during start up to get to the config menu, where you can restore factory defaults. Hopefully this will help.

  • Keys 2 and 6 also work on the X656de.

  • For lexmark X543 to restore to factory defaults, turn off printer then hold down the tick symbol and right arrow together (on the printer control panel) and turn back on, once dots on printer's screen have counted above 4 dots release the buttons. Printer will initialize and then you will see a new menu - Config Menu - scroll to Factory Defaults - press tick. If networked printer you will have 2 more options - select Restore STD Net for a full total back to factory out the box reset. See here for full instructions

  • 2 and 6 work for the X564de, but if there's a configuration password set you're SOL.
