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

Hi, This is the second time I have reset my waste ink counter in about 18 months. Disappointed that the key I ordered (OS X Mac version) came to me as an exe. Luckily I had anticipated this and had a PC at the ready. That of course worked like a charm. Thanks anyway.

I purchased four activation keys total, but I had an issue using one. John at tech support got it straightened out and I was able to complete the install on the printer. Now I can set up the CISS unit for Sublimation printing. I'm very happy, and can testify that this product works to unlock the firmware of your printer. (Epson WF-3720)
