DF 7100 stacking problem.

[kyotechnz]

Have a DF 7100 Finisher on a TA 2554ci copier.
It initially had a stapling and stacking problem. Replaced the stapler which fixed the stapling problem.
The stacking issue I am having is when it is stacking the paper to be stapled it does not every time stack the paper properly so the staple misses some of the sheets or not aligned properly. The first sheet is correct, the next sheet may not be.

Checked the Finisher and all mylars, static brushes and guides are correct (at least they appear to be).
Firmware is up to date.
The annoying thing is I have tested the Finisher on a machine in the workshop and it operates fine.
I have also taken our own paper to the customer, their paper is a bit curly, to run in the machine on site.
The machine still would not stack the paper for stapling consistently.
The only thing left is the copier.
At the moment we are all out of ideas, first one of these Finishers we have had play up.
Needs some ideas to point me in the right direction.
Anyone had a similar issue?

Flip the finisher on it's side and you can get to these little fingers. They are what pull the paper back in to the compiler as on previous models. When new, the fingers are square on the end. They become rounded when worn. If you don't have any, you can flip them over to get a fresh edge.

tmaged I did check those and they appeared to be fine, also if they were the problem I would have expected them to create the same issue in the workshop when I tested the Finisher.

In first attempt i suggest to see if putting paper format manually change something. If the problem persist and on another mfp the df works good I think there's a problem with paper timing.
