Epson stylus DX7400 stopped working with E light. Reset using free trial key and now works again. Thank you.

Used the WIC utility to reset the waste inked counter (after cleaning the pads). Worked perfect! Printer is an Epson XP-710

gracias me salvaron la vida para los que no se han dado cuenta cuando nos pide la clave y es nuestra primera vez pongan la palabra \"trial\" sin comillas y eso soluciona por lo menos por un tiempo

I replaced the waste ink pad assembly on my Epson XP-800, not understanding that there were internal counters needing to be reset. The WIC Reset Utility and the WIC RESET KEY, along with the replacement waste ink pad assembly, have restored my printer to me. Thanks for making it so easy and, most importantly, having it work like you said it would.
