I would clean the two vert tran clutches. just like, I think it was a j21 on a km-420. Sometimes there is too much grease on them from the factory

Jam code 61. Kyocera says also to replace conveyance clutch for possible too much grease on clutches from factory.

I agree with replacing those clutches, but they are electronic clutches and can't see how grease are used on them. The conveyance unit is different from the veritical unit. I would think as tonerkiller says its, the vertical transport unit clutches, and they are just plain faulty. check the parts list.

We got 2 of these "302GR44120 CLUTCH FEED" ordered to replace on the VERTICAL FEED UNIT. Seems to be the only solution suggested so far.

I have cleaned the vert clutches for this problem. There is a white grease on the clutch face so they do not rust in transport. I know that does not make sense, but I have seen it a few times

setup lots of these machines, but never seen the issue really. I don't print lots of pages on setup, just a couple to make sure all the feeder ect. work. Have heard about it from the guys in the field and all type of resolution have been mentioned inculding the vertical transport unit clutches. Here is the situation though. There are 5 more of the identical clutches on this machine, 1 on bypass, 2 conveyance, 2 drive section and the 2 on the verticall unit.

Replaced the 2 clutches on vertical transports of both machines.. They came with a smaller clutch than book shows/ different part number. Had 3.5w clutches and replaced with the correct ones that were 4w alot bigger clutches in size. No further jamming issues with either machine 15k prints since change of clutches.
