I have a case with an iRC3580i.
Only 2-3 first copies/prints have wrinkles on the sheet. The other consequent copies/prints are fine.
If the machine gets in a stand by state for more than 3-4 hours or at the beginning of the day the wrinkles happen.
I did replace fixing unit and pressure rollers and bearings (not only for this reason but because it was time to replace them).
Machine has about 0.8 mil copies
I have been telling customer that the reason is humidity - even if I don't believe this at 100 %.
Now my question is this :
Am I lying to the customer ?
