KM-5050 PF-750 random jam code 12

ok thanks but this one jams without a code and has a feed unit sitting right above it can that be replaced?

Have a look at this post:
FS9530 w/ PF750 = jams

The plastic features that secure the left side pickup roller typically break. There is a new style feed frame, but there is a better solution. Drill a #40 hole through the metal flange that is flopping around, and tap the metal M3 x 0.5. Remove the metal plate and enlarge the hole in the plastic to #31. Countersink the plastic from the bottom side, so that an M3 flathead screw sets flush with the plastic. Assemble.

I have heard that the new style feed frame breaks in exactly the same place, and takes quite a bit more work.

You need to look and see if you have an older version of this feed. There are plastic tabs near the feed tires and that assembly that the rear front stay will break off and cause jamming issues.
There is a bulletin about that I will try and find but there is a newer model frame with a beefed up set of catches that I have yet to see break. That's where I would start.

These symptoms are remedies are spread out over several weeks. It started with Jam 17 code when pulling from the right side of the PF-750. I followed the manual and replaced the conveying clutch. Then the machine got a jam code 12 very randomly. After speaking with Kyocera, they said to replace another clutch. I went ahead and replaced all 4 clutches in the paper feed unit. I found one of the wires to a clutch was pinched and another clutch had a broken metal tong part. (the teeth that keep the clutch in place) All that was replaced and I am still getting a Jam 12 code randomly. I plan on checking all electrical ends again and replacing the feed tires, mylar that goes to the sep tire, and torque limiter. I have a feeling this wont help though. Ideas?

Also, if anyone has replaced these clutches maybe you know. When you take out the paper feed unit, there is a clutch that is farthest to the rear of the machine. Are the metal teeth on that clutch supposed to be around the metal of the frame or above it? On a machine I looked at they were above the from piece just loosely over it. I thought that was wierd, but Kyocera had no idea nor a machine to look at with me.
