I updated my printer's firmware, and now my product shows that the ink is not recognized. What should I do?
From time to time, Epson updates its firmware to ensure the printer operates as designed, and the printer is designed to work only with genuine Epson-brand cartridges. Other brands of ink cartridges and ink supplies are not compatible and, even if described as compatible, may not function properly. Please replace any non-Epson cartridges with Genuine Epson cartridges.
Epson provides information about the design of the printer on the box as well as many other locations including materials shipped with the printer.
