I just wanna say THANK YOU for saving me a few hundred dollars, my Epson WF-7710 which i converted to a sublimation printer stopped reading my cartridges because the chip reader on my printer was missing a few connectors that reads the cartridge, (they break off very easily) so i was doing some research and i came across this website, i was very skeptical because there's alot of SCAMMERS out there, i could of easily ordered 4 more chip readers from Amazon but i know it will break down the line once again so i took a chance and ordered the chipless firmware and i gotta say I MADE THE RIGHT CHOICE, installation was a breeze and at the end my Epson WF-7710 is back up and running like a brand new machine. So i'm very very happy and i will refer anyone who needs this chipless firmware or any other product from here. THANK YOU VERY VERY MUCH.
