Maybe this has been posted before but it just bit me. New Epson firmware updates will add a restriction so that your printer will only work with Epson print cartridges. I happened to have aftermarket cartridges in mine and had no trouble at all until after the update. After the update the printer will not print unless it detects Epson cartridges.
There are several on line sites showing how to roll your firmware back and get your printer working again.
