Oh boy where to begin on this one, let's start with the duplex:
-adj SIM 8-20. Don't go too crazy or you will get background.
-adj SIM 43-1 values A and B way down.
-make sure it has a "Z2" transfer belt installed with serial # of the belt at the rear.
-clean sensor and run SIM 44-3 -drum potential sensor.
-try changing paper or in the large cap trays, try flipping it over. Sounds stupid, but it eliminates it as an cause.
And as always, make sure the firmware is up to date. You can also adjust luminosity in the soft switch settings but its a long shot.

the new transfer belt, and firmware, have fixed the issue for our machines that were doin that

I also have a machine doing exactly the same, always when duplexing. It appears to be flipping the lead edge at the drum seperation. Speaking to other Engineers, this has always been a problem on this model. Sharp did modify the transfer belt and drum sep pawls, but my problem is on a brand new machine thats only done 200k, and the machine has latest spec. I would be interested to hear if anyone has an answer to this as well.

have ordered another transfer belt will see what happens with a new have turned down sim 43 1 to 160 c on a and b made a bit of diffference

Just tried machine with good quality paper and fault has disappeared . As soon as I switched back, the fault reappeared.. Tried Navigator Universal as opposed to the recycled rubbish they were using.

Hi guys,

here we have same problem but without any solution.
firmware is f00 so should be updated (or not?).
Belt is Z2
Sim 43-01 put both A/B values to 160 degrees

Paper is not so bad. it's not "navigator" but it's ok
do you have any clue.
Thanks a lot for your kind help.

Hi Guys, we had something similar on an mxm1100 (new). After long runs we would get POIND_N jams, as well as a couple of other jam codes. Went down the paper route with no joy. Turned out to be the reg motor. On long runs it would heat up, bind, and slow down. Dont know if this will help you.
