  Printer EP-806AW I bought a clear key because there is a limit on waste ink. It was very helpful because I was able to solve it safely. Thank you very much.  (JAPAN 2020/11/07)

  I replaced the waste ink pad assembly on my Epson XP-800, not understanding that there were internal counters needing to be reset. The WIC Reset Utility and the WIC RESET KEY, along with the replacement waste ink pad assembly, have restored my printer to me. Thanks for making it so easy and, most importantly, having it work like you said it would.

  Thrilled to bits - I thought my trusty printer was destined for the scrap heap ( although nothing wrong except it would no longer operate due to "ink pad full") and I would have to buy new, until I alighted on your product . Also if the ink pad actually causes problem tyou advise where I can buy a replacement kit and do it myself. You perform a great service to printer users. Well done!
