Roller marks from Epson 4800

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!

Had the same problem with some of the same papers on my Epson 3800. Under paper configuration, set paten gap to wide, and paper thickness to 5, and use the rear manual feed. Problems disappeared.

It sounds like that is the trailing edge when it comes out of the printer. Mine do it sometimes too. Don't worry about the platen gap or thickness, just use the manual feed.
