Greetings,
My HP Photosmart C4580 hangs after start (frozen).
I cannot operate the menu due the printer doesn't respond to any button.
I believe its something related with the wireless encryption but now I can't do nothing.
I need to do a hard reset.
I read something about leaving the printer disconnected for more than 30min, a tutorial to do a soft reset (I believe) pressing keys (but the menu is not responding to any key pressing).
I appreciate any help.
