I've been working on several Di5510/7210 machines and I have in several of these lots of trouble with paper jams in the finisher, mostly when the paper is going out of the machine and into the finisher. Is there any known issue with these kind of jams?
What are the jam codes..there are numerous areas that jams can occur including the exit area of the machine itself so the codes are needed to identify the area.
your problem could come from one of many different things. Depending on which function you are accessing, the paper uses one of two gates at the exit end to leave the machine. The fuser has a gate that shifts to send the paper out. Taking the finisher off will cause the paper to exit straight out of the fuser. Does it jam often enough for you to see a difference right after making a change? You could try swapping fusers with one from a good working machine. I have had one where the toner leaking from the drum carriage would be carried to the rollers in the finisher, making them slick and causing jams. If the de-curl roller { black soft spongy one } in the fuser is worn , it will cause the end of the paper to curl and cause jams. I also had one where the spring that holds down the 11b gate had the end broke off causing the end of spring to rest on the shaft behind it, which was the gate that has to shift to send the paper out. If I took the finisher off, it would not jam because it did not movew that gate. This led me to think the problem was in the finisher, which was confusing. I hope some of this helps, Good Luck!
There is an issue where the wiring harness to the main tray exit sensor will fatigue and break a wire. I was able to get a idle jam while moving the wires around. J72-29 when printing and J72-(can't remember).

Best way is activate ,,47,, and move with responsible harness
There are 2 one way bearings on the front of the fuser that will cause jamming all day long in the finisher. Just pull them and clean or replace and you will probably have solved the problem, I do believe there is a bulletin covering this also. Try yanking the one way from the paper exit drive gear and clean and/or replace as this will also cause what you are experiencing. Not sure what kind of meter the machine has but if the bearings don't fix it start looking at the sensors as they can get worn in high volume situations.
One of the one-way bearings mitchl referenced drives a foam roller, that roller get soft and dried out and will cause jamming problems. I believe this is the part number for it is 4024-2713-01
I was sort of hoping that he would give us an indication of copy count on the pig which can be a great help as to what parts may need to be freshened up....... God I hate this series of machines, with a passion!
I have the same problem on my 5510. This machine has been refurbished and shows around 85000 copies. I have a very strange problem. If I make copies from hard copies it works fine but when I try to print from my computer, the machine prints and stops the paper at the exit assembly (it exits about 2" out of the machine and then stops) and give me paper jam. I disconnected the sorter to see if this unit was causing paper jam, but the sorter is fine. Also, if I try to make double sided copies, it makes copy of one side and exists the paper and stops just like it stops when I try to print from my computer and gives me paper jam. Any help will be appreciated? thanks
I think you have a problem with your turnover area of the ADU. If you make copies from the platten glass do the copies exit face up or down?
When you print from a PC, they are always face down therefore have to be turned over. In your case it sounds like that is not happening...hence the jam!! Check the turnover guide is working!
