Thanks John I figured it out.. I didn\'t read things as well as I should have.. and panicked a bit. The good news is my Epson 1280 printer is up and running again thanks to your manual. George

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.

Looks ok, working fine, save a lot of time in my case, finding a bad sensor in 15 minutes, but can not read counter information`s. Only can reset.
