  It is end of October 2021. I just have bought the second reset key in my printers life. The first one I bought in 2015 !!! That means my printer had already it's life prolonged by 6 years and goes now into the second reset cycle. Keep up the good work to prevent valuable electronic hardware becoming garbage. I never had any trouble in 6 years with the ink waste pad after resetting the counter for the first time.

  I was a bit dubious about buying and downloading manual, never having used this site before, but I'm glad I did. With it I was able to sort a problem on my printer. Without it I wouldn't have known where to start. Thank you. Steve Goodey.

Reset key is for ONE USE only
One reset key - One Reset
It is clearly stated in reset key description!

  NOT SO SIMPLE IF YOU ARE A MAC USER. I WASTED 3+ hours trying to download and activate on my MacPro. NO SUCCESS. Took me 20 minutes to install on my spouses' WINDOWS PC. OK....printer is functional again but it has NOT been a pleasant experience.

  It works perfectly to make Epson XP-55 chip-free and disable ink levels. Many thanks.

  Sure wish your live support was online. I could understand it being down on New Year's Eve, but not today. I sent an email to this effect also, but no reply. The reset key worked, thanks. For just half a day, however. Not what I expected for $9.99. Please advise.
