I just purchased two Ricoh Pro C7200 with the 5th color. It replaced Xerox Iridesse that was overkill for our volume. I also have the in-line GBC punch which we had on the Iridesse. My problem is a lot of jams when running through the punch. We currently run 28lb Hammermill Premium Color Copy paper and since it was jamming on both printers I am leaning towards the paper as a possible cause. I am curious to know what brand of paper is used while using the GBC in-line punch. Also curious to see if others are having the same issue with the punch. Thanks.
