  I tried using the free utility Epson provided, the counter reset to 40%, then after a print I got the error again. I gave WIC a chance out of desperation and it work! Saved me from throwing out a perfectly good printer and buying a new one. I use CISS and do a lot of prints and head cleaning. I cleaned ink pads myself but will set up a waste bottle when I get the chance.
