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.

i reset with the key that i got and nothing worked. it still shows that the carts are not genuine. what a waste of time. it sat here for 12 hours on the "do not turn off printer" epson wf-7210.... give me back the $30 i spent or give me more keys to try again. order #18740047 =============================== According to your Order number - You have purchased RESET Key ($9.99) which is required for Wate Ink Counters reset. If You want to downgrade firmware - You have to buy FIRMWARE Key ($19.99)
