We installed several of these machines at 1 location and are only having problems with 1. Right out of the box, we installed these machines all with 3000 sheet decks and this one started jamming at the duplex area right away. (JAM 61). It only jams when feeding from the paper deck. The other 2 drawers will run all day with no jams. We cleaned duplex clutch and rollers, everything in the paper path, etc. to no avail. We replaced the entire feed section and board of the deck with parts from a new machine, but no help. Finally, i called the hotline and they said it was a known problem and a tech rep said the solution was to replace the feed clutch #3 in the machine. Sure enough, went 1 week without jamming. This morning, it's back. Anybody seen this and, more importantly, found a successful fix? We are getting desperate here. Thanks in advance.

I'm having the same issue with a 520i, new out of the box. I have been able to try a different 3000 sheet paper feeder, entire duplex/conveying section and a middle feed assembly to no avail. I did clean and swap the vertical feed sensors around which stopped the problem for a couple of days, but returned again. I am going to replace these sensors but don't believe this is the fix. -
We had one exactly like that and it wound up being the lower clutch in the verticle transport. In a brand new machine that clutch looked like it had gone 300K. Cleaned it and it went away. Think they outright replaced it after that. The clutch I mean..not the machine."Some days you get the bear, some days the bear gets you."

Deciced to replace the vertical feed ass'y which has fixed the issueComment

Changing Conveying Assy definitely the resolution!
We had this problem on a 520i with a PF-760 out of the box back in January. The machine only jams from the PF760. We went through the same things, what finally solved the issue was replacing the entire conveying assembly. Apparently [at the time] the KMA stock of replacement clutches had the same issue as the originals as ordering and replacing just the clutch only solved the problem for a few days. We have not had the issue since then.Comment

I went back to the location and removed the new clutch we had put in and cleaned it. We are waiting to hear the results. So far, it has been okay, but last time it was a full week before the prioblem returned, so we'll see. Thanks to all.Comment

Re: TaskAlfa 420i with jam 61
Still getting the same problem with conveying springs doubled and spacer installed.
Symptom (intermittent and moody): 1st piece half pass duplex switch actuator and the lead edge of the 2nd piece stop right on FSW1.

Re: TaskAlfa 420i with jam 61
What I dont understand is that it only happens with 3000 sheet feeder. If it was fine without it, why would the sudden addition of paper feeder be of any difference? (It was on a cabinet for a while)
I've checked the jam log too, no 61's prior to this addition.Idling colour developers are not healthy developers.Comment

Re: TaskAlfa 420i with jam 61
This sounds similar to an issue I ran into with a customers 520i, only problem is cannot duplex 2 side to 2 side from high cap drawers... 1-2 side ok, 2-2 ok from standard drawers, but will jam every time if trying 2-2 from hi cap....Comment

Re: TaskAlfa 420i with jam 61
The machine I worked on only jammed first few pages in the morning. I had been out 3 or 4 times and hadn't seen anything. On the last visit it jammed pretty consistently first thing in the morning. The clutches were in good shape, with less than 50K on them, but I cleaned anyway.
Some of the early Mitas were fussy as to how the clutches were shimmed. I noticed that the gear & disk side of the duplex clutch did not spin freely. It had two shims (0.50mm and 0.25mm). I removed the 0.25mm shim and it spun nice and freely. Then did the same on the pre-registration clutch.
The customer says it works flawlessly. I haven't seen the machine since. Maybe this will help you. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.
