Replace the clutch pack in the back, some people clean them but I had never any luck with that NONSENSE.

It is much easy to replace transport drive assy with all clutches

I also faced this kind of problem,I ve try change the feed clutch (transport) assemblly ( all of the clutch,if not wrong 4 clutches)changed the registration clutch & roller.its work only for a few copies.I have three of this machine.so now I let the machine just take a long rest in the dark room.
these machine already runs about 1m,400k and 600k.

If any tech have better solution are really appriciated.

I replaced more than five transports (drive assy with gears and clutches),and never had any problems for long time. Costs in EU are about 150 EUR ,and it is better to replace drive assy than you replace only clutches.So this is my advice. Good luck.

of cause I changed the drive assemblly and it still the same,

If you have not (Z fold jam),means that resist roller is OK,tray to change this small peaces,once I took very long time to solve this problem (actuator was not in original condition).
AR505 PG 21 Vertical transport unit
MLEVP0758FCZZ AE C Vertical transport actuator

Sorry if I am wrong!

me also so sory .actually mine problem is the image have vertical white line.from top to bottom-A4 sideway.I suspected the pre regist roller push the paper toward the regist roller and make a too big buckle between the pre and regist roller.initialy the problem is Z folded paper.after changed the transport clutch assemblly then this problem came.I means vertical line.

Is there any diferences if you make some changes in SIM 51-2 ?

To the point:

Sharp had issues with to much grease on these, by changing just one, you will be back for the others.

The right thing is to replace all five clutches at once, this cost about $75.00 plus a shit load of time to do it.

Or you can buy the whole unit for $120.00 and get it done within a hours time.

I made my decision years ago on this.

I will assume that you have verified that the rollers are turning and your clutch is energizing the roller drive . if so you can go into simulation and change the timing of that clutch.
