I bought a HP Color LaserJet Pro MFP M479fdw today. It was easy to install and soon the first picture was printed. When I turned it on again later it said: "A problem has occured with one of the printer's critical system files. A printer update will be installed to fix this problem." Since then it is not doing anuthing and I cannot reach it by IP adress, USB, WiFi or it s own menu screen. I was hoping to give it a factory reset without the touch screen. Is this possible? Thanks for any help!

You cannot reset without the screen working. If it is bricked and it is brand new, I would return, pain in the butt, but best option.

Repairatrooper, thanks for your reply! It's not a complete brick, may be. I see it's wifi but it's secured now (as opposed to being open at first), and I don't know the security key/password. I tried 12345678 and 00000000. Do you know the default password for it's own WIFI connection, which is visible om my laptop (but not accessible)?
