I got my new Summa S2 T120 today and tried it right away. I was told that the middle roll has less pressure than the 2 outer ones, so I tried to position the small piece vinyl correctly between the 2 outer rolls. I simply folded up the middle roll manually but the middle roll was not under any gritroll, which gave me an error message when reading in the size, now my question is how do i cut small pieces like this if i have 3 rolls?
