    SC750 on MPC3000 w/ SR790

    Headed back out to this one for a 2nd time. First time around I swapped the shift sensor even though the old one showed up as good in tech mode when flagged and unflagged. I ended up unplugging it from the wall with and when that fixed it I assumed electrical demons were the cause. Headed out with firmware and fingers crossed it's not the board.

    Anyone else run across this one before?

    Samir: No, not again. I... why does it say paper jam when there is no paper jam? I swear to God, one of these days, I just kick this piece of shit out the window.

      The tier2 knowledgebase says...

      [Cause]
      The motor stops because the shift tray lift motor's torque is insufficient.
      When aided by hand, it turns.

      [Resolution]
      Replace the shift tray lift motor (AX050277).

          Everything moves properly, even when the code is kicked. The tray moves up and down and actuates the sensor. I updated the machine firmware Anne that made no change. I recall an issue with the MP4000 and a firmware/EPROM incompatability whn they first came out. This one has B4085161 in it, so I'll be checking that out next when I get back to my laptop.
