Mike,
My bad

I didnt read your post correctly, i was in a rush when i seen it. Sometimes my 1400 will just feed unprinted sheets thru, I think it has something to do with it not feeding correctly or the vinyl or paper not being cut square, but i am not really sure & would like to know for sure what is happening, as it can get frustrating at times....
I didnt know that 44" was the max length, I seen somewhere where it was 19", so thats what i have been cutting my vinyl to, glad to know it's 44" now i can really pump out some stickers

I do know from experience that if the vinyl is not cut square on the ends, it will causes all kinds of feeding issues(sometimes kicking a blank page out) & which causes the print to be slightly off, which then causes the contour cuts to be off....
