  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 am very, very grateful that this helped me in resetting the school printer. it is very hassle (avoiding corona virus spread) in my part to carry the printer from my place transporting via boat to the city (travelling for at least an hour by the sea) but with your help it solved my problem we can now continue the printing of the modules and self learning materials of the children since the classes will start on October 5. good job!

  I don't like throwing something (a printer in this case) away and consuming our earth's resources (buying a new printer) just because Epson make it difficult for me to avoid doing this. I wish Epson would make products that can be maintained by the product owner and this way contributes to the well being of our planet. This reset utility worked 'as described' and now, having cleaned my ink pads, I can get more value from the printer I already own. Thanks for this reset software.

  Your Epson C42 Service Program worked a treat to clear the counter. So easy even I could do it

  I bought refillable cartridges for the Epson XP-241 on AliExpress and did not work. The reason: Epson XP-241 manufactured in the Philippines. I was desperate. The solution: CHIPLESS. You've saved my XP-241 printer. Thank you very much.

  Really terrific service and rescue manual and a very helpful and approachable team of people. The very small expenditure indeed saved me the price of a new printer.
