I have HP PageWide Managed MFP P77740z. (MB part number: A7W93-80153-A, A7W93-60153, (AKL570800389 REV. A))
I believe, it has faulty motherboard - turns on, is trying to load progress bar and shows blue error 8b380001. I can't detect it under network (LAN) or with USB.
What issue it can have?
I believe, it is a firmware issue. Maybe someone could help to reflash the firmware?
Or maybe someone could confirm that motherboard from machine like P77750Z / P77760Z (Motherboard part number: A7W93-67084 A7W93-80153X10) would work with my machine? I saw to buy P77750Z refurbished. Wondering if it will fit to my printer. The motherboards looks the same in pictures...
I can't event find the difference between P77740z and P77750Z.
