Hi john: I wouldlike to let you know that i bought another reset key from yoy site and it worked with onother workforce 840 I owned. i think the problem with the other printer workforce 840 was that I used the reset key epson has in their website some times and probably it bloked the printer. Just for you to know and to let you know this time worked with another 840 I own Thank you for your understanding and for refunding the money when did not work. It says a lot of you business reputation

I was amazed how easy that was. I was in doubt that this simple download would work... with my heart racing! I entered the key,and there it was, all fixed. 2manuals, I must say, what you said it would do, it did, and I\'m so relieved and happy, and can work again. The success of this has made me want to write a review on your product right away. Thank you so much Robert Dorsey President/CEO Cabin Watch Fine Time Wear
