If you print on Ilford Gold Fibre see if you can get the rear feeder to work. I continue to get a skew paper error. It's no big deal as the paper is thin enough to go through the sheet feeder without a hitch but I'm always concerned about the paper getting jerked around a little as it sets in.
Not got that particular paper, but I tried several different Innova ones I use and, manual feed does seem noticeably better than when I tried the 3800 a while back. The only problem was a sheet of paper from an old box, with a bit of curl, it took a couple of goes to get it to go in.
A (slightly) curled sheet of Epson TPP went in OK - I don't actually use this paper much since it's a bit too flaky/dusty/fragile for my liking.
