sharp mx 5111n copier jamming frequently

[dcooper]

I have a sharp Mx-5111n that has a mx-fn11 finisher when duplexing occasionally i get a dogear fold towards lead edge front of paper and
it jams right at the entrance lever of finisher. I can sometimes run about 250 copies without a jam but once it starts it jams about every 25 copies. A few times I had to turn machine off and back on cuz it jammed at he registration sensor. Turning machine off seems to reset the sensor. When it jams I get a
FED_N code in test command 22-3. Sometimes there is a little tear in the paper but most times no tear but jamming at entrance of finisher. I don't see any problem by eyesight in paper path. Is there something I should be looking for a solution for the paper jams? Thanks for your help

Re: sharp mx 5111n copier jamming frequently

There is a white mylar on the upper part of the finisher entrance that can move and causes the sensor flag to stick causing this jam. You can reposition the mylar or just remove it (as I do) and it should take care of your jamming issue for the FED_N jam. We've had this happen on a lot of these finishers I can see why the mylar is there but it's not really necessary.

Good luck.

Oops I just realized this is a different finisher than what I was thinking of but still worth a look see.
