I have a C350 (160K) that is intermitantly jamming (single sided) on the exit from the fuser unit into the exit tray. When the jam occurs the last 2 or so cm of the sheet is left under the exit rollers and the machine registers an exit jam.

A new Fuser unit has been fitted, the exit sensor checks out OK and the jam will occur on all types of paper from both trays and bypass.

From the type of jam, it looks like a one way bearing is intermitantly slipping, but where? can anyone give some ideas before I strip out the Fuser Drive assy.

Thanks
