  Reset key itself WORKS, hurrah! 5 stars. BUT . . . it was a struggle to get the download. Our MacBook which is a few years old does not allow the download to be installed because Apple blocks "unrecognized developers." That should be taken care of or a warning should be placed on all promotional materials related to WIC RESET KEY. I was able to get the download onto my old Apple desktop which has not had operating system updates. That's how I finally purchased the reset key. Please tell me why the whole business of the reset key, after replacing the ink pads, is not an example of contrived malicious obsolescence? I was tied up for hours, cursing the Epson company, and a breath away from buying a new printer, adding plastic waste into our environment. I liken my experience to changing a car's oil filter and then needing a code to start the car again.

  My Epson 1400 got the end of life message and I had already reset it once before so I couldn't use the Epson site to reset it. I remembered this site from years ago and purchased the utility reset and it worked like a charm. Only wish I had not spent $400 on a new printer before remembering your site. Anyways I just did a live video showing that this really works on my youtube channel. More people need to know about this remedy!
