Did you look at the troubleshooting guide in the service manual for the 5100? I don't know if it shares the transport or not... (5300 service manual attached)
I have it up and running but I think part of the problem is the "open" switch for the drawer- either it's dirty, or it requires an extended press to register I want it open. I plan to open the front and clean the switch and see if that solves that issuue.
Otherwise, it seems to operate normally. Sounds decent too.
