We have two Canon ImagePress C700's, and one C850. We are having an issue with size and back up. For example, a job with crop marks that should measure 17.5" from one end to the other will be as much as 1/16" too short, and the back up on 2 sided items can be 1/8" or more off. We have gone in to the paper catalog and made adjustments for each paper weight, type and size, and that works for a few days, then we are right back to the same issue. Are other people having this issue? The company that services these machines says nobody else is having this problem. Do Ricoh or Xerox printers have this issue? The size issue isn't a problem so much in the short direction, usually just the length. All 3 machines have Fiery controllers. We use lots of 80# and 100# gloss text, and cover, as well as 60#, 70# and 80# offset, all digital cut to size papers.
