The fact that the paper is double-sided may be making this worse. The matte paper I usually use (red River Polar Matte) has a treated surface on the print side. double-sided papers of course have the treated surface on both sides, so the bottom rollers are working on a lower-friction surface.I don't know if that has a practical impact, but it seems like it might. I did use some sheets of double-sided Polar Matte, and they worked fine, but again, that was with a flat feed.
