We have 2 of these machines doing the exact same thing. They jam when duplexing (j20) and the copies are really crooked. I don't think it has anything to do with duplex section as the jamming is a result of the copies being so skewed when pulled thru the machine. If you do single copies you can see that the test chart is really crooked, severe at times. I have checked all of the fs1128 posts as this is a bigger version of that clunker. We have checked the reg. roller, mylars, cassettes, all paper guides for burrs, etc. and nothing has been obvious. I haven't checked if it did it thru the mp tray, which i should have. Any ideas?? One of the machines is in the shop, has been taken apart and reassembled but the problem is still there. The jams that are removed are identical to each other from each copier.....if we fix one, we fix both! There is a fan that cools the engine pcb that is right in the middle of the paper path and the guide has slots in it where the fan is mounted.....thinking this might be pulling paper crooked before it gets to the reg. roller area(?) Help!
thanks protec. i checked the dev unit on the one in the shop and the metal guide looks o.k. i will see if we have another dv unit in stock at least to try to see if the skew changes or goes away. i will update this post if i find a fix.
We had a bunch of these doing the jam 20. For the quickest fix we do is shift the cassette guides by taking the gear on the guides off shifting it 3mm to the right and put the gear back on.
I tried to shift the gear in the cassette but that didn't seem to help. I actually bent both side guides in the paper cassette. The guides are metal and in my case i bent them to the right. It made a huge difference as far as the centering of the paper/test chart. I ran 100 duplex copies with no jams and the copies looked straight front and back.
