    We had to send back to Japan all CR4.5 MFP boards for repair and they returned them once fixed.

    We sent back over 40 boards, they repaired most of them and sent them back to redistribute back to Sharp Direct and Sharp Dealers.

    Had something to do with some of the flash memory chips on the MFP board.
    THEY seem nice people.
    You got these repairs for free? And who are they?

    U2-74 on MX2651

    Any idea how to fix U2-74 on an MX-2651 and related models?

    We have a lot of machines throwing this error for some reason.

    Manual says to update FW...but obviously this has already been done.

    Any other suggestions?
Working...
