I spent 4 hours trying to get my r340 to work then l I used your program to reset the protection counter. I have just printed 5 pages and 4 disks. Slightly cryptic instructions but it worked perfectly. it took me all of 5 minutes.

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.
