    No. It doesn't respond to the buffer lid being opened/closed. I've been suspecting that for some reason it's not supplying power to the buffer pass.

    If I remove the buffer pass completely, the main unit will still function, so I don't think it's a drive belt. The only connection to the actual buffer pass is a cable, and I'm starting to believe that it's not supplying power to the buffer anymore.

    Simple checks,
    did u check the Printer side cable connection for 24v output voltage supply to buffer end connection ????

    DC pcb--J126 Pin 2-24v ---make sure the connector is in place on controller board
    did u check the buffer connector cable (interior back end connection inside buffer unit)

    I meant the drive belt in the buffer pass itself. break out your meter and do the checks Teckat has suggested
