  Just wanted to say thanks for your prompt service. I received the manual and have printed it.

  The trial key is key (pun intended). It unblocked my EcoTank right away through Wi-Fi. Soon I'll have to buy this key. This software DISABLING of the printer should be illegal. It's programmed to actually brick the device. Unbelievable. Talk about planned obsolescence!

  Fantastico... funziona tutto perfettamente. Grazie mille

  Thank you so much for the reset. I was able to clean my ink pads, and then using your reset utility, reset my printer and now it works perfectly! So much better than buying a new printer!

  I downloaded Epson's maintenance utility and couldn't get it to work. Found the WIC Reset Utility and it worked like a charm! Will buy the full reset key when I get my kit.
