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.
