My 4800 just started showing two parallel lines about 1/4 inch apart on the right hand side of a landscape oriented 8.5x11 print, about 1 inch in from the paper edge. They are very faint lines that look like a roller or some other very faint rub mark. I ran a print on the roll paper just prior to printing with the 8.5x11 and I don't see any marks on those prints.

I am using Hahn. Photo Rag Satin 310 and Epson Enhanced Matte. Marks show up on both papers. I have run dozens of prints with these papers before and never had an issue.

Any ideas? Thanks!
