Only to confirm it worked like a charm on my Epson 1410 (australia) Thank to you for this huge saver.

Success! I installed a OctInkjet waste inkpad overflow and tried their reset to no avail - they furnished your link. Your reset fixed my RX690 Epson printer within minutes . Ink started to flow into the overflow immediately (just as well it was installed). I did apattern check-all six colours perfect. Thank you Brian

I love printing hard copies of material to review. I bought an Epson EcoTank 2650 for the single purpose of never having to worry about how much I have to print. When I found out about the ink pad and how it basically “fills up” and prevents you from printing, I was pretty pissed off. I called a service center in my state in the US and they wanted $110 to replace the ink pad and reset it. I searched hard for a solution and when I found this I was really sure this was a scam. I tried it from one of your affiliates (octoinkjets) and did the trial to reset it to 90% and it worked. Thank god you guys have this tool. I bought a key for $10 and was done with it. Watched a video on how to clean the ink pads and it was super easy. Now I have a new printer basically. I can’t believe Epson gets away with this crap. You guys rock! It really took a leap of faith to try this.

Awesome. I made a mistake ordering 2 codes (I needed just 1). They called me (I'm in Italy) to ask if it was an erroneous "double click"...and they deleted the second order. I still can't believe it. That's PURE QUALITY. (Of course the whole thing works and the printer is doing his work). THANX!

I have an epson artisan 800. I tried using the epson waste ink counter reset tool, but it was worthless. I used the 2manual reset utility and it worked perfect, resetting the counters to zero. It was so easy to complete.

This is my second purchase today, for the same utility. Purchased under \"ian@cinnamoncafe.com\", had no end of problems. Once I paid the system did not let me in. Tried to change the password and it sent me 3 updates to the correct address, then informed me that the e-mail and password where both incorrect. Still have no joy. Decided to register again at ian@jonesi.demon.co.uk, and everything worked smoothly!

I was very happy with the ease of ordering & installing the WIC Reset Utility Key. My printer is up and running once again after I replaced the waste toner box. THANK YOU
