I've now followed your advice, used a plastic ruler with a very clean fine linen handkerchief held on it, lightly dampened with alcohol, against the friction wheel as I operated the feed mechanism - I did that three times - and the printer now works 100%, with not a single sheet failing to feed in. I could make it work by manually 'helping' the paper in (using 250gsm non-genuine matte photo paper), and even risked holding very fine sandpaper (YES!) as the printer tried to feed (to clean the coating from the paper off the friction wheel) - but to no real avail. I've had a massive problem of paper not feeding into an Epson R390 Photo Stylus printer. thus there is a bit of an understanding of electronic control of mechanisms. and have been involved a bit in automation (robotics) of test equipment. My background is Aeronautical Engineering. PERHAPS USING A STICK WOULD BE A BETTER CHOICE. BE CAREFUL THAT THE FEED DOES NOT PULL THE CLOTH INTO THE ROLLERS. and a second or more later the printer went through a feed cycle. and pushed the paper feed button on the printer (top right button). then carefully holding the wet cloth to the rubber wheel. I wet the end of the cloth with rubbing alcohol wrapped at the end of my finger. I then decided to clean that wheel with rubbing alcohol and a dishcloth.
throwing the timing of the whole process off. there is a rubber covered friction wheel which is meant to pull the top sheet through.
then using a flashlight and watching the feed mechanism at the bottom, right side of the paper. I called Epson's tech support, and talked with the fellow for about 90 minutes trying all his ideas (which did not work). I would try to guide the paper and slightly push on the top during the feed process, but then it would take the paper, and push it right on through the printer without printing. I would try a single sheet, and had the same problem. and it would not correctly feed the paper into the printer. I was using the Epson 13" x 19" Ultra Premium Presentation Paper (formely Enhanced Matte).
