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.
