  Hi john: I wouldlike to let you know that i bought another reset key from yoy site and it worked with onother workforce 840 I owned. i think the problem with the other printer workforce 840 was that I used the reset key epson has in their website some times and probably it bloked the printer. Just for you to know and to let you know this time worked with another 840 I own Thank you for your understanding and for refunding the money when did not work. It says a lot of you business reputation

  Ich bin begeistert! Mit dem TRIAL Key konnte ich meinen Epson XP 750 wieder resetten und er funktioniert wieder. Vielen Dank, dass ich mir dadurch das Geld für einen neuen Drucker sparen konnte und ein Drucker weniger die Umwelt belastet. War nur etwas anstrengend, die englischen Anweisungen zu lesen und zu übersetzen. Es wäre schön, wenn es diese Seite auch auf Deutsch gäbe.

  Malgré une méconnaissance en informatique, j'ai facilement débloqué mon problème de compteur ! Merci beaucoup

  Ce logiciel a le mérite de fonctionner en WiFi. On n'a donc pas besoin du câble USB. Pour 8.54 € (9.99 $) j'ai facilement réinitialiser les compteurs de mon Epson XP-610 qui était bloquée. This software has the advantage of working over Wi-Fi, so you don't need a USB cable. For €8.54 ($9.99), I easily reset the counters on my Epson XP-610, which had frozen.
