  Dear Team WIC, I was ready to buy a new Epson R800 printer today after failing all weekend to get my printer to work despite trying every technique suggested on the internet including the SSC Service Utility that still doesn't work for whatever reason?? Thank you for your help and the printer is working 100% wonderfully again now with your reset utility!!! GOOD is not enough of a rating for your Firm - GREAT is much better *****10/10***** Much appreciate your service :), Ivor.

  Hello - just great! Greetings from Germany - Es funktioniert auch mit dem Epson PX810FW perfekt - einfach hinten per USB anschließen und das kostenlose Programm laden. Wenn der Drucker gefunden wurde, den Reset Key online per PayPal kaufen. Habe sofot den Key per E-Mail bekommen. Jetzt noch 3 Klicks und der Drucker ist wieder wie neu.... Danke und Gruß

  Apart from the first key that I bought that did not arrive, the next 2 keys I bought arrived (I've only used one so far) so I'll save the other one for next time. Thanks very much for your help. Shelley Hamilton.
