First, Epson papers ( Legacy Baryta, Platine) are almost never flat causing the paper not to load properly. I have had this issue with even larger sizes such as 13x19. Most of all the printer will just not take 81/2x11 paper. I have tried "smoothing" the ends and every once in a while the paper will go through. However, I destroy several sheets each box every time. And the paper is expensive. I have adjusted the platen to widest and the pressure roller to 3. No help.
Anyone had this issue? I believe Epson papers are flawed in the manufacturing process and just are not flat. I have sent boxes back to Epson and they had the same issue with the paper I was using and replaced it. However, Epson should do a better quality control process.
