I’m working on a Minolta DI 450… Jamming at exit… Replaced exit guide plate the exit door and transport unit….
At first I assumed it was the exit guide plate.. Replaced new with new one. But still jams…paper is not wrinkles and it stops right at the exit….. The paper stops at the exit either if I’m using sort or not (face up or down)……

Checked counters and some indicated the transport unit… replaced the whole transport
But still there is the jamming at the exit (no finisher)
Any help???

Is it jamming every time? I would look at the exit sensor, it is above the top exit guide plate. The actuator can stick and be slow to operate, also the sensor can pop out of position. Are the fixer claws for the top fuser black or brown? The brown ones can cause jams. Also the web needs to be working correctly. My bet tho would be the exit sensor!

I have had issues with the door not being closed the right amount, or the gate not being in the correct position. If that gate at the top of the exit door is not moving correctly the paper will stop.

If jamming only when copying face down its the sensor under the yellow cover.
Besides of this, the large spring clutch of the fuser drive unit in the machine can cause this (just beside the stepper motor) . Remove any grease and retighten the clutch arbor firmly.

If the sensor and guid plat did not solf problem.
Check fuser drive. there is a gear with a spring on it. spring some times start slips.

Are the sheets actually coming out face down? I had an issue one time where the turnover guide was cracked and instead of going into the turnover section it was coming straight out throwing off the timing causing jams everytime.
