  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.

  Absolutely brilliant , this small utility saved me from having to replace my Printer. Had I known of this sites existence previously I am sure it would have saved my Epson 580 which I just through out.

  Wow, this software really works! I was very reluctant to purchase the reset key, but after taking a few minutes to read all of the instructions and figuring out how to prepare the printer and computer...it was a breeze. Thank you for saving my printer!
