I just downloaded and tried your WIC Reset Utility. Since I am running Windows 8.1 I was afraid that it might not work too well. I was WRONG!! Happily it works GREAT on Windows 8.1! I\\\'m a happy camper!! Just thought I should let you know!! Best regards, Deepak

If you've replaced the heads, or removed/re-installed them, you need this! Also does a power nozzle clean - worth the money just for that. Note it needs DOS or a DOS box in Windows.

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!
