aficio 1035 with Sr 720 jamming

[leo34staffs]

Hi guys,
On the finisher, the paper seems to roll up inside the finisher and cause a jam when stapling (not all the time) , is there something to look for here or is it possibly the paper being poor/damp?

hi, try the foam positioning roller, they perish, or the belts snap or come off.Check the various mylars and side fence sensors.

Good luck

This is usually a paper issue. Try flipping the paper over. Also try a better grade of paper. The dry paper or paper in a paper wrapper will curl in the fuser and jam in the staple tray.

...and of course try a different ream of paper (maybe other brand).
I had the same problem with a new unit 23K on it and it was the paper...even the customer didn't liked...I just love no name brand paper...3 sheets with the fibers LEF 3 with fibres SEF...but people love it cause it's cheap....

I'm glad that there are other people seeing this issue, I have seen it regularly on these finishers and have diagnosed everything from leveling the machine with the finisher using plywood, replacing the static brush and connecting extra ground cables to the frame of both machines, verifying that the electrical sockets were grounded properly, and the weirdest one that I didn't expect to work with Office Depot paper; flipping over the stack in the tray.

What I did end up doing with one finisher was take it back to the shop and run a thousand stapled pages through it. I then cut off the end that was stapled and ran it through again in the same direction, 2000 pages, with no jams.

Now this showed me that it was wither their machine, their environment, or their paper (I was using our shop stock. Not the best, but not Office Depot random paper) and I have subsequently found that it is dependent on the paper, and if it curls like you mentioned, it can sometimes be flipped over to go against its natural curl and increase odds of success.

What I tell people now after I bring out a different stock and show them what I'm talking about, is to use the good paper in a different tray for stapling; and default to the cheap stuff for everything else. Alot of them don't want to do it, but that's the price of buying paper that is not quality controlled and bought on the free market and then packaged under the same brand.

Unfortunately there are better finishers that control the curl better, but this one is not designed to handle extravagant curl.

Thanks for the replies there guys, im sure its to do with paper and what you say has confirmed it.

A good idea what you said, is to have a tray with decent paper in for d/s and stapling and perhaps disabling double siding on the other trays.

Thanks for the pointers.

It's not a broken junction gate is it?
I know these can go quite regularly.Just a thought.

I have all the time with me a fresh ream of RICOH paper. It not a premium grade but it's good enough. No arrow on the ream to indicate the paper curl but performs pretty well in our machines.
This is the easiest way to test and troubleshoot the feeding and jamming problems and to demonstrate to the customer that it's a problem with the paper they use.
I can not blame all the cheap brands...some time it's the way how customers store the paper...just last week I found in a school paper made by teachers...they tried to cut it to 8.5 x 11" and you can imagine the results...
