  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.

  Absolutely fantastic. I got the error message and removed the ink pads ans washed them, don't think I got all the ink out though! Then I used this program as a 'trial' and it worked wonderfully, Printing all OK again and I thought I would need to buy a new printer. When it happens again, I will purchase new pads and a reset key - has to be cheaper than a visit to a repair shop or a new printer. Thank you so much

  Ich bin begeistert! Mit dem TRIAL Key konnte ich meinen Epson XP 750 wieder resetten und er funktioniert wieder. Vielen Dank, dass ich mir dadurch das Geld fĂĽr einen neuen Drucker sparen konnte und ein Drucker weniger die Umwelt belastet. War nur etwas anstrengend, die englischen Anweisungen zu lesen und zu ĂĽbersetzen. Es wäre schön, wenn es diese Seite auch auf Deutsch gäbe.
