All was well with these cartridges, and overnight (this occurred between 2 sheets of the same document), the printer to my attention that the black cartridge was not recognized. After black cartridge change, even an original is no longer recognized. The printer is dead, and an internet search seems that he is not an isolated case: the NONAME cartridges burn the chips used for the recognition of Epson cartridges. In short, to save on cartridges dees, I have to switch printers!
