  This tool is badly wrtten, after downgrading using the wrong firmareware version I was unable to purchase another key as it thought it was a duplicate order, tried online help waited a hour and gave up, in total I have wasted £40 on a CISS system thats not reconized by the printer, and £20 on the WIC tool that although was my fault, I can remedy because I can't puchase another key

  Hi. I tried to reset printer Epson EP-901f (japanese model). I tryed everything possible I could - SCC utility, soft reset,.... so far no luck. Then i bought this and it reset my printer just in second. Thanks for good job. My printer is back to life again. I paid for this printer about $550US. Now I can use it again just for spending extra almost 10 dollars. It\'s worth it. Thanks for your great job. Well done!
