Is it possible to add another pinch roller or 2 to the roland sp 300v?? Instead of 2 you would have 3 or 4....that way if for paper or material got off a little it still wouldn't mess your print up?? Some times when im printing something 8-15 feet long and I get to the end of the roll of he media...the media tries to walk on me ....if it had more pinch rollers it wouldn't matter...
