Konica c6501 jam code J-1702

[eifling]

Have a machine that constantly jams with J-1702. I have cleaned wheels, cleaned paper path. Still I cannot find any reason it should be jamming in the duplex. 1 sheet will always jam as its making the curve to come back up out of the duplexing section. Anyone have any ideas?

How many copies are on it? I bet it has a few, replace the actuator that leads down to the duplexer (it's right under the fuser and it's NOT the fuser exit) I find that if you put a drop of super glue on it, that should help till ya get it replaced. If it looks like the end of a finger and NOT the end of a chisel then it's bad.

Turns out, one of the moters in the duplexing section had came loose and was able to spin when it would turn on. It would turn on its axis until the wire stopped it, i guess over time it kept yanking on the wire which eventually broke it. No wire>No motor>Wheels not moving>Jam.

Replaced the wire and the machine is happy.
