I just downloaded and tried your WIC Reset Utility. and then made the purchase of the KEY. It worked perfectly. Do I need to get new pads? Install a waste bottle? or do nothing for 4 more years?

Worked hassle free with my Epson XP-55 . I am very thankful that you provide the SW tool also for Linux as I have gone Microsoft-free at home. It's cool that you provide a trial license to check out, whether the counter reset works in your setup (I admit I was sceptical). It worked for me and I immediatly ordered the full license. The good thing is: as it is pure SW, it works also on weekends, when you need to print urgently and that stupid printer decided to not let you print any more!
