  Looks ok, working fine, save a lot of time in my case, finding a bad sensor in 15 minutes, but can not read counter information`s. Only can reset.

  My printer stopped printing with the error as \"General Error\" Epson quoted me $60 to send an engineer to fix my printer. After reading through the information on this site I decided to fix it myself. Found the problem was related to the waste ink pad counter. Only 10 minutes, I had the the printer working. The printer tested fine and has done approx 150 pages since with NO issues. Thanks for your WIC PROGRAM!
