XP322 ran out of copies and froze up. I read up that it was an Epson device to sell more printers but discovered your site just before treating it to a display of bad temper. The 20% of extra time will make the replacement question easier and i can use my stock of ink up on this 4 year old printer. I may even use your services to zero life the counter as it isn't a bad device really. Thank you so much.

Bought a key for a epson rx425 although they delayed to send me the key to my email,they finally send and i saved my printer,the ink cartridges i had bought, and a lot of money i would have wasted to buy a new one.Old printer working as brand new!THANK YOU ALL!

la clé a fonctionné 1 mois après 150 copies je ne sait de nouveau plus utiliser l'imprimante. J'essaye de contacter wic reset utility en vain... je ne recommande donc pas du tout l'application ======Reply======== You have used your key not correctly. Please try once more time.
