Password lost - HP LaserJet Pro 400 Printer M401 series

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

Try : turn printer off   - hold down the 'X' & left arrow   - turn printer on  ...keep holding for a few secs...Then release  keys...

 

It should have done a NV RAM reset....

Hello DoublHH,

 

Thank you for your answer. This printer doesn't have any physical button but the power button. It's a touch screen. :smileysad:

I found how to do it :

 

After performing an NVRAM initialization, reconfigure any computers that print to this product so that the computers can recognize the product.
1.Turn the product off.
2.Perform one of the following steps:
●LCD control panel models: Simultaneously press and hold the right arrow button and the Cancel button. Keep these buttons depressed as you turn the product on.
●Touchscreen control panel models : Press and hold the lower right quadrant of thetouchscreen. Keep the quadrant depressed as you turn the product on.
3.When the Permanent Storage Init.message appears on the display, release the buttons.
4.When the product has finished the NVRAM initialization, it returns to the Ready state
