Re: C451 false jam
is it the fuser or the duplex unit its complaining about.
its not uncommon for the central duplex unit actuator to fall out resulting in a permanent jam state.
The fuser itself reporting a jam will be the sensor on the exit guide assembly on the door or the registration sensor under the paper dust remover, check they are operational.
the actuator under the fuser is a fusing loop sensor, make sure its not snapped or growing a beard.Comment

Shows jam indicator as lower inside large door that opens on right. Nothing shows jam in service mode.

Re: C451 false jam
Of course last sensor checked and swapped at non op side of duplex cleared it! Only problem now is jam leaving fuser going into the gate on the upper part of door. Swapped the sensor on that an still jams. Fuser is pushing it up as it gets folded so what's the deal now???

Re: C451 false jam
if the exit guide assembly isnt turning, and i think thats where you mean its jamming, then make sure drive is getting to it - if the drive bushing from the fusing drive unit with the little white gear on it under the exit belt drive assy is flogged out the gear wont drive the exit belt drive assembly or the exit guide assembly on the right side door.
shouldnt be hard to work out whats going on now.Comment

Re: C451 false jam
Hi there!
The most common probem is the 16 T-gear A00J895300 (partscatalogue page 60 #16 ), it causes a lot of the squeeking problems & jams. I change it after 50-70K copies/prints.
Hope this helps.
