Hi guys, newbie posting so go easy 
Been to a customer today with an stacking offset issue
As pages of 10 or more sheets become collated 2/3 sheets of the stack become misaligned and as a consequence mis-stapled
The user runs 1000's of these per month
These are almost always 2-sided and high colour coverage on both sides
We had a few spare finishers in the warehouse so swapped with spare but has had no effect
Things I've tried (on old and replacement):
Strip finisher and cleaned all exit and return rollers and cleaned and checked sensors
Adjust the fuser setting to alternate 4 to reduce heat and speed also try light paper setting
Upgrade firmware to latest so both machine and finisher are in sync (52.390.1)
Adjust alignment via dip switch settings on finisher (though I hadn't done this before but found in service manual)
Things to mention:
All consumables running are genuine but the fuser is at 20% and rollers look slightly wrinkled
Paper being used is Q-connect plain 80gsm which thus far has working fine on a variety of other 6040's and M880's in the field
I no longer have use of CSN so don't have access to the latest updates but have the CPMD (may 2019) and service manual and other useful docs
In conclusion:
I was thinking of going back in with a new fuser and possibly fresh ream of alternate paper (xerox eco paper)
I do have a document pulled from CSN regarding M880 finisher alignment/adjustment but nothing for 6040
I realise these machines are quite dated now and have been dogged by fuser issues
Any constructive advise more than welcome
