  Much easier then I had expected. Downloaded the program, purchased the key, switch off and on the printer and that was it! The printer works again.

  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

  This update helps to recognize compatible cartridges or continuous system with self-resetting chip that I stopped recognizing due to firmware update in Epson WF-7510 Printer.

  Whenever I try to do the ink charge, ink out appears here, so far it hasn't worked for me, could support staff be able to help?

REPLY: To use Ink Charge - ink levels must be more then 50%
