I bought a key Only for this when I run a reset for is to give me a QUERY IS REJECTED then it goes on to say system has broken pieces and for me to buy another key and try again. And this is not on the list of error codes! I can't afford to keep buying keys! What a RIP OFF! Robin Beyer

I'm not going to lie I was very dubious, but the proof is in the pudding it does work and I'm a happy bunny. My printer is the Epson Photo PX810FW one of the newer models so feel confident in using this system.

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
