Need to reset my HP LaserJet Pro 400 M401n to factory settings

[BrotherRock]

I do not remember the password to access my HP LaserJet Pro 400 M401n printer.  In fact I do not remember setting one up!  But then I am an old man  The menus have all been disabled on the LCD.  The instuctions in the manual do not work since the menus are disabled.

Restore the factory-set defaults (LCD control panel)
1. On the product control panel, press the OK button to open the menus.
2. Open the following menus:
-Service
-Restore Defaults
The product automatically restarts.

Please advise.

Thanks in advance

Hello BrotherRock,

I am sorry, but to get your issue more exposure, I would suggest posting it in the commercial forums, since this is a commercial product. You can click here for the link.

I do not know what you mean by "commercial" .  I bought this printer for my personal use.  I am not a commercial enterprise by any stretch of the imagination.
