I have a customer with a PF-760 and she says it jams when paper gets low. I cannot get copier to jam. I replaced rollers and clutches in the feed unit and I checked the tab that holds the feed roller bracket down that usually breaks and that is ok. Has anyone had issues with jamming out of the large capacity tray.
Not sure if this will be of any help, but empty the PF760 of all paper and let her put brand new reams of paper in, then remove all but a few on each side and see if it will run empty. Customers aren't always careful loading paper and I've seen paper get offset in the cassette due to improper loading, also new paper out of a freshly opened ream should be checked for dog eared sheets at both the top and bottom of the stack. I know that I, as a tech, can fully load all cassettes with paper and get the machine to run jam free, but the next time they, the customer, loads paper, that they sometimes will get jamming issues, because they either don't remove the dog eared pieces or the load paper into the drawer and exceed the max paper capacity that the drawer can handle, which is very common.
After running copier a while I discovered jam is caused by 3000 sheet finisher. About every thousand copies I will get a jam 87. Paper will be crunched in conveying tray of finisher. Has anybody had this issue.
I know that this is pretty much not marked on reams of paper any longer, but it should be. Does anybody remember when the difference between "Short" grain and "Long" grain paper made a difference. I had one once, on a KonicaMinolta 7272, would randomly jam in the finisher. If the copy job was run with less than 4 pages in the group to be sorted and in 11 1/2 x 8 orientation, Jams would randomly occur. This was with 20# paper, simply by changing the orientation of the paper for these type jobs to 8 x 11 1/2 would correct for a slight paper buckle occuring on eject which in effect caused the finisher to not see the lead edge of the paper at the eject sensor in time. Try running the job from one of the other trays oriented different, or try running a slight heavier weight paper. I don't think you will be able to find paper specifically labeled as short grain or long grain any more unless you go to a specialty paper provider or possibly a print shop.
It could be the paper. They are using recycled paper, but this will be hard to convince to the customer that it is the paper because the customer has a CS400ci with the same 3000 sheet finisher on it doing the same volume and that copier does not jam. The jam I did see was in the finisher in the pull out conveying unit crunched up as it was going down in the conveying unit but this happens every thousand or two thousand copies(j87). The CS552ci has latest firmware.
I talked to my rep and this is whats the temp fix. place washers about the thickness of a medium paper clip under the metal brackets that holds the feed rollers. I tried it and worked
