  All I can say is THANK YOU!! Thank you for allowing me to roll back (downgrade) my Epson XP-410 printer\'s firmware with ease!! A couple of clicks, and I was downgraded. This allowed me to use non-oem cartridges that would not work no matter what I tried with current firmware (Epson updated firmware just to battle the use of non-oem cartridges). The money spent will be saved with the very first refill of these refillable cartridges I bought. I was skeptical, but it really was THAT easy! Winning the battle against Epson!! First time I\'ve ever paid for a \"hack\", well worth it!

  Double thanks John, I now have a working printer. It was so quick and easy I thought it hadn't done anything, then I tried it... Best regards, Richard

  I got the flashing lights and Service required message on my Epson R2400, as many others have before!
I spent hours online and eventually managed to download Epsons own Adjustment Program. It showed me the waste ink settings but would not let me reset the counter, although I had disconnected the feed tubes and re-routed them to an external bottle.
Today I found 2Manuals.com and downloaded their WIC reset program. I thought It probably won\'t work but one key is only $9.99 so what the heck!
Well that was the best $9.99 I have ever spent - as soon as I entered the key and hit RESET the printer whirred into action, ink pumped into my waste bottle and I am back in action!

This has saved me a lot of money and the hassle of sending the printer to an Epson service centre. Truly a 5***** product! Chris Porteous, Prestatyn, U.K.

  Thank you! The trail reset key worked very well on my Epson Expression XP-610. I'll be back to buy a reset key.
