Hi David,
Thank you for using the Support Forum. You have contacted the people we would have had you contact. Let's hope someone that has an Iridesse may have seen this and can offer some advice.
Seemingly at random, pages will be shifted towards the machine side by .5 inch, or exactly 2 punch holes. The image is not shifted on the page, nothing is skewed. It is completely unpredictable, sometimes 5 times in a 30 page book, others no shifts for 2000 sheets. On site service and analysts have told me that if I didn't have a sample in hand, they'd tell me that's not possible.
Any experiences with this out there? Avenues to chase help?
-Dave
