tried what you said and got exactly the same result, grabbed paper and sent it all the way through without printing
the dimensions I was trying to use was 19" x 13". I tried using a 8.5" x 11" Velvet paper that would not grab and them regular typing paper that also would not grab on its own.
Your printer evidently has a problem with the rear feeder. It's not the size of the paper at all, since normal sized paper just feeds through.I suspect that a paper presence sensor is either defective itself, or the circuitry sensing it in the printer's circuit board(s) is defective... either way, the paper, when the printer 'grabs' it, is not sensed as present at first, so it feeds in endlessly... until the printer's inner works detect abnormal paper too far into the printer, whereupon the printer feeds it all the way out as it kind of should.Your printer will require servicing, unfortunately... unless, looking into the rear feeder, you see a jammed or fouled switch/sensor element that can be unjammed easily. (If the printer is less than a year old, measured from its date of purchase as a new device, then its failure is covered by Epson's 1-year warranty, and Epson ought to fix or replace it for you for free if you put in a claim for failure-within-warranty. Let me know, if this is the case, and I will advise you further.)I'm sorry to come to this conclusion, it must be a disappointment. But the symptoms are pretty clear. And the reset and queue-clearing you went through should have gotten rid of any sort of rogue print job or odd glitch or temporary condition of the circuits of the printer. Replacing the printer is another option, of course... it's up to you as to which option to pursue. I can advise you a bit as to either choice, I hope.
