I have a new Epson 3880, very impressed with the out of the box performance with Epson's luster paper and ink.
I do notice, with the 13x19 epson luster, top feed, that there's a kinda plastic/ratchet sort of sound as the paper advances maybe a bit before?). I don't notice that sound at all when printing on 8.5x11 paper. I haven't spotted print defects that would indicate a platen gap problem, nor did changing the platen gap from auto to wide seem to change behavior.
Any chance that sound is normal? Any specific things I should be looking for if it's not?
