As the comments before me, these cartridges do not work and are not recognized by the printer, which grows to only buy Epson. It's very random: sometimes it recognizes, and suddenly refuses to print and does not recognize the cartridges. I am obliged to install a new one, while the old has hardly begun, to print and pray that it does not duplicate the shot. What interest to buy cheaper if it is to be at its 5th non emptied cartridge?
