          Most often it is the door sensors in the bridge units. Even Ricoh has mentioned this to me on phone support before.

              Ditto that, power on jams are an interruption caused by an interlock opening (bridge unit covers the the most common culprit). It could possibly be another interlock, finisher door, front door or right side. Try jiggling them and see how much play you have.
