  I was skeptical, like I'm sure we all are when buying something new online, but I simply turned off my Epson Monitor, under maintenance tab, bought the key, turned off my printer, then turned it back and and IT WORKED! Well worth $10.00, just so I don't have to buy another printer.

  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!
