    ARM620 E7-90 E7-80

    This machine keeps popping up E7-90 and E7-80

    I know these are both PCU communication troubles. I have reseated all connectors from PCU to scan board to the MFP board.

    The codes clears out for a short time 30 mins to an hour and comes right back each time. It will usually lock up the entire machine (cant press buttons of go into sim). I have flashed machine with no difference in problem. I am guessing replacing pcu board. Any other suggestions out there? Ive worked on tons of these machines and never had this issue on one yet. Thanks for the help.

    Any accessories? If there is a fax unit, try unplugging that. Not really specific to that machine but a good general thing to try.

        Symptom: E7-90 trouble (The cooling fans turn on and off (twice) before staying off and the display locks up with "hanging logo").
        Cause: Faulty Mother Board - replace.
