After hours of trying to reset my Epson Stylus Photo PX710W I found Waste Ink Counter reset utility - I purchased the key and it set my counter back to Zero - The printer is now working again. Next time I buy a printer it will not ne an Epson. Alan

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

I tried using the free utility Epson provided, the counter reset to 40%, then after a print I got the error again. I gave WIC a chance out of desperation and it work! Saved me from throwing out a perfectly good printer and buying a new one. I use CISS and do a lot of prints and head cleaning. I cleaned ink pads myself but will set up a waste bottle when I get the chance.

I got the flashing lights and Service required message on my Epson R2400, as many others have before! I spent hours online and eventually managed to download Epsons own Adjustment Program. It showed me the waste ink settings but would not let me reset the counter, although I had disconnected the feed tubes and re-routed them to an external bottle. Today I found 2Manuals.com and downloaded their WIC reset program. I thought It probably won\'t work but one key is only $9.99 so what the heck! Well that was the best $9.99 I have ever spent - as soon as I entered the key and hit RESET the printer whirred into action, ink pumped into my waste bottle and I am back in action! This has saved me a lot of money and the hassle of sending the printer to an Epson service centre. Truly a 5***** product! Chris Porteous, Prestatyn, U.K.
