Have you clean/replace the finisher paddles above the eject assy

Yes forgot to mention those.
However as I said in my post the first set is ok, its the second set and on that has the problem.
The only difference is that the first set goes straight through the fns and directly into the stapler whereas the first sheet for the subsequent sets reverses and is held in a guide where it waits for the second sheet to arrive then they are both exited to the stapler area and the rest of the set goes on top.
I have a feeling that this is where the fault is but cant quite nail it down (yet).

Re: Fs537 staple issue

So the alignment plates aren't squaring off paper or the paper doesn't sit back far enough in finisher?

Worth dropping the fuser temp to test the theory. Had similar issues with finisher stacking.
If the paper is of a poor grade flip the ream upside down to see it that reduce paper curl.
In that case get better paper.

Re: Fs537 staple issue

Does this finisher have a reverse roller that tamps the sheets into place for stapling??? Or is it the side guides not tamping the sheets into position???[emoji848] It's also possible that there's either a bad stepper motor that is skipping steps or a problematic driver board missing steps--failing driver chip. Many times if a stepper is not driven at the proper current for a particular load, it can also skip steps!!!...which would probably indicate a bad driver chip.[emoji57]

Indeed tough one. Only few pro-masters can catch such sort of problems. Thanks for following up with solution.

Re: Fs537 staple issue

We just had a similar problem with badly aligned A3 paper in staple mode. It was basicly the first page that was "out of line".

We renewed the paddles, tried different paper, modified the paddles with longer ones - everything with no major success.
Finally we changed the angle of the paper exit tray with some washers between the 2 brackets on the tray assy and the machine and voila, problem was gone.
