  Hello there, I am interested in buying a license key to make my WF-5620 chipless. Firmware upload is completed, I have fear I may have problems with your windows application and firewall. Do you offer support to make the License app work ? Thank you, resetters ! =========== Yes sure

  Oh my golly, I didn't think that would work, but it fixed it in about 30 seconds. Even though I hadn't been able to disable the process monitor thing that it says do first, the reset program still worked instantly when I ran it on an Epson XP-540. If there is one thing that gets my goat in terms of being so unethical both a rip-off financially and environmentally unsustainable, its the way printer companies rip us off. So am super grateful to have found a way round this. For a much more reasonable price than the printer shop told us, and something I could do at home when I needed the printer urgently for work! Thanks so much!

  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)
