I have an ImagePress C750 with Staple Finisher T1 with a jam 1124 on the finisher.

Machine has approx 1.8 mill.

I have already cleaned everything and greased at the 2 arms as per a bulletin.

The problem is that when it jams - it jam with every paper (regardless of the curve adjustment on the media catalog).

If I run heavy stock - half of the sheet will come out and than stop
If I run plain paper - it will round up inside.

Did someone come to a solution ?

Peace..
