I have a LaserJet M1522nF, and the problem when I working on is that it is freezing every time so I decide to update the firmware. During the updating the device was down because of electricity so I turned it on again and there is a message on the small screen saing
HEWLETT-PACKARD >>
After nothing appeared on screen the device seems to be blocked or the firmware was corrupted.
Now, how can I reset the update of firmware or how can I reinstall it?
