very easy! Buy Key, Open Program, Enter Key. You are all set! Make sure to actually check your waste ink pads or install an external tank. Great I can finally squeeze the life out of my printer. Epson scam artist want you to send it back so they can sell as a refurbished model. I really don\'t know why epson doesn\'t just make this program available them self for free? Until then I can pay $10 instead of a new epson. Tested on WF7510. Owner of Epson WF7110 - New arrival looks to be good so far Epson WF7510 - Good Scanner Epson WF7010 - Work Horse Epson WF1100 - Second worse Epson WF30 - worst one Epson c88 - Ancient
