We recently got a few HP Color LaserJet CP2025dn printers. I first set one up and set a password for it. When I moved the printer to a different network and tried to set up the network again using the LCD panel, I found that I was unable to do it. There was a message displayed on the panel.
Menu access is disabled
I then realized that whenever you set a password for the printer, the LCD panel access is locked. You can only configure the printer through the web server on the printer. However, since the network was different, I could not access the web server on it. My only option was to reset the printer and configure it from scratch. To reset the CP2025dn, do the following:
That was it. After resetting the printer, I was able to configure it with the new network setting.
