  Works slick...and why shouldn't they make some $$ for their key and Utility? I appreciate not having to send the printer to Tech support or buy a new one like Epson suggests- when it was a piece of cake to do myself.

  Oh my golly, I didn't think that would work, but it fixed it in about 30 seconds. Even though I hadn't been able to disable the process monitor thing that it says do first, the reset program still worked instantly when I ran it on an Epson XP-540. If there is one thing that gets my goat in terms of being so unethical both a rip-off financially and environmentally unsustainable, its the way printer companies rip us off. So am super grateful to have found a way round this. For a much more reasonable price than the printer shop told us, and something I could do at home when I needed the printer urgently for work! Thanks so much!

  My Epson R260 quit working- read up online what the cause was (counters in printer). I downloaded the WIC Utility package and sure enough the counter was at 100.70%. I downloaded the Reset Key- at first it didn't work. Turned the printer off & on as instructed. Still didn't work. Finally I turned the monitoring on- reset the printer. Then turned monitoring off again and reset the printer & it finally worked. I think the monitoring just got hung up somehow- computers!!! I'm very thankful I'm good for another few years. It only cost $9.99 instead of the price of buying another printer (and I have all these ink cartridges that would go to waste)- OR a repair bill & would be without it while being fixed. Would I buy another Epson printer- NO- but would I recommend 2manuals for the fix- Definitely.
