The printer displays a message that the installed cartridges are not genuine Epson ink. If you try to print a test page or whatever, the quality is terrible; very light to the point of being illegible and bad or colorless. It's a lot cheaper than new genuine ink, but if it's useless it's a much worse waste of money.
