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.

Thanks for your advice. I had the printer Epson Pro 4900 attached to the network. Once I used the USB connection everything worked great. There were 2 ink channels that I could not clean. After poking around the internet I found discussion of air in the lines. Did an initial charge and now things are working perfectly. Thanks for a great product and tech support. Regards, Morris Gven

I just downloaded and tried your WIC Reset Utility. Since I am running Windows 8.1 I was afraid that it might not work too well. I was WRONG!! Happily it works GREAT on Windows 8.1! I\\\'m a happy camper!! Just thought I should let you know!! Best regards, Deepak

IT WORKS! IT WORKS! IT WORKS! I tried the free reset key through Epson.com but their servers don\'t work anymore and there\'s soooooooooo many errors. After hours of frustration I paid the $9.99 saying, \"What do I have to lose?\" Just like the other reviews said, you\'ll be all set within 2 minutes.>The reviews have spelling errors (ha ha) so real people are writing them. And to leave this review that I\'m writing, the site made me log in (proving I have an account and truly am a customer that tried it). Worked on my Epson Stylus CX8400.
