I have a Ir3045 with a S1 finisher that jams on 17" paper. It feeds just over half out of the finisher, then stops. The trailing end of the paper is fan-folded in the entrance chute of the finisher. It looks as if the finisher slows down for paper delivery, but the copier does not and shoves the paper into the entrance of the finisher. Sometimes, the paper does come out without jamming, but has a ruffle at the end. Anyone have any clues? Sorry, I did not write down the jam code.
