I have a brand new 570 with 012-114 jam codes. Paper is jamming going into the booklet maker. It is always the first sheet going in and is very intermittent. It might jam 4 times out of 500 sheets. The paper size is 11X17. It looks like the first sheet is catching on something on the front side. I compared it to another finisher and everything looks identical. It also does it on 70 lb paper. Any ideas?
