Hi all,
We have a HP LaserJet Pro 400 Printer M401 series(touch screen model) ans one fo our former employee applyed a password. Nobody knows this password and we need to change the IP address on the printer.
I'm looking to do a factory reset. From what I found on the user guide, the procedure would be :
Restore the factory-set defaults (touchscreen control panel)
1. From the Home screen on the product control panel, touch the Setup button.
2. Scroll to and touch the Service menu.
3. Scroll to and touch the Restore Defaults button, and then touch the OK button.
The product automatically restarts.
The issue is that when I touch "service" menu, the password prompt blocks me from going to the next menu. Is there an other way to do a factory reset on this printer ? A physical button somewere ? Something to do with the power button may be ?
Thank you for your help !
Oliver
