I do not understand how little AMAZON yet worked with this company. The cartridges are not recognized, and given the other reviews, this is the easiest to work with dorigines cartridges more expensive quite sour. In response to several comments, There are several solutions: this is the first to boycott EPSON printers that block their equipment if you have the misfortune to install cartridges else than their own. The second is the purchasing power groups as well AMAZON else, to organize a round table between manufacturers, distributors and customers, to find a solution that suits everyone. The manufacturer will understand that only little lon continue to hijack the clients with buying overpriced cartridges, the risk of winning the jackpot.
