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

Changed the waste ink pads with the new ones and used WicReset for reseting waste counter on Epson L382. Received the key without any delay, right after placing the order and paying for it. Worked perfectly. Counter became 0,00%. Great utility!
