  I don't like throwing something (a printer in this case) away and consuming our earth's resources (buying a new printer) just because Epson make it difficult for me to avoid doing this. I wish Epson would make products that can be maintained by the product owner and this way contributes to the well being of our planet. This reset utility worked 'as described' and now, having cleaned my ink pads, I can get more value from the printer I already own. Thanks for this reset software.

  Excellent , i was a bit dubious about buying a key in case it didn't work or that it could be a con , but im very very happy i did get this utility & purchased a key . I used this utility to reset my Epson SX-110 which was giving me the message " ink pads had reached the end of their life " & needed service i ain't paying £49.99 just to have a sponge replaced , so a big THANK YOU for the tool & I WILL TELL MY FRIENDS WHO HAVE PRINTERS ALL ABOUT YOU .
