I have an Epson CX6400 multifunction printer and use generic disposables from Choice Stationery. The printer obviously recognises that these are not genuine Epson parts. Every time I print, a pop-up screen appears reminding me I am not using Epson cartridges and asks me to confirm I want to proceed. A bit of a nuisance really but is there any way to disable this screen or is this simply another way for manufacturers to annoy (punish?) us for not using their own overpriced cartridges.
