Biz 223 tray 1 jamming J-1101

[copyman]

Paper feeds barely an inch past the sep roller. Tried 2 different paper feed units, one rebuilt with new rollers and mag clutch "cleaned with contact cleaner", same thing happen. Then took tray 1 from a working machine in the shop and same identical jam. Paper stops same place every time, registering J-1101 in jam history. SM says transport motor, paper tray feed clutch (what are chances of 2 different clutches being bad?), main pwb, registration sensor. I've only had to replace paper feed rollers for jamming on these.

Didn't see anything in the bulletins or solutions

Any ideas greatly appreciated.


Thanks

With this series the first place I would start is removing the registration section and clean or replace the registration bushing. They get gummed up and cause jamming.

It sounds like it does not even get that far

Like rrr posted it only feeds less than an inch, "barely" past the sep roller so registration wouldn't come into play. Lead edge stops same place every time. The SM does mention the registration sensor causing J-1101 code, it is the last thing on the list and something I'll probably try. The SM has transport motor first on the list for causing 1101's. Looks like a bitch to get to so might try the easier things first maybe someone will post that M1 does go bad. Only have maybe 20 of these that I still work on. All low volume so I haven't needed to do much on these. Hopefully flip them all into 224e's within next year.

Thanks again

If the registration bushings are gummed up the transport motor gets bogged down trying to turn the registration clutch and the feed unit at the same time.

Thanks copier addict, makes sense. I'll try your suggestion. Is the transport motor M1 exclusive to tray 1? Like I posted tray 2 is feeding fine. Looking in the manual it looks like M1 is for both trays?

the black one way bearings that drive the feed rollers are likely slipping. remove them, scuff up the shafts and clean the bearings with IPA and thats that

When using tray two, the feed unit has stopped turning before the registration is fired.

Thanks again copier addict and Syn. Forgot to mention in original post the rebuilt unit I tried had new one way clutches & shaft scuffed up. This is different than intermittent jams that happen with bad rollers or one ways. Paper is stopping 99% of the time after only feeding 1/2-1". Same exact jam every time. I'm hoping it is something as simple as the reg bushing gummed up. Will report back.

Wanted to add that it was working fine and started jamming few months after customer started using machine. I just sold this off lease machine recently so don't know the history with it. 80k clicks

hey i know it makes a difference from a 423 using a slower feed assy, there is an extra sensor in the 423 feed assy, i wonder if anyone put a 423 feed assy in a slower model if it also causes jamming due to pinout change?
