The problem with your printer could be just a paper dust build up, cleaning the paper guide ways could help. Nothing reality to loose as its that or trash as they are a disposable item.
The other thing it does not have going for it is that it is an Epson, we had one fail at 13months, Epson said its out of warranty, buy a new one.
We did just that, bought new ones, we now have two Canon printers an A4 all in one and an A3, both offer great prints, are reasonably economical with ink.
