Ink Cartridge Specifications
Note: Your printer is designed to work only with genuine Epson-brand ink cartridges. Other brands of ink
cartridges and ink supplies are not compatible and, even if described as compatible, may not function
properly or at all. Epson periodically provides firmware updates to address issues of security,
performance, minor bug fixes and ensure the printer functions as designed. These updates may affect
the functionality of third-party ink. Non-Epson branded or altered Epson cartridges that functioned prior
to a firmware update may not continue to function.
The included initial cartridges are designed for reliable printer setup and cannot be used as replacement
cartridges or resold. After setup, the remaining ink is available for printing. Yields are based on ISO
24711 in default mode, printing continuously. Yields vary due to print images, settings, and
temperatures. Printing infrequently or primarily with one color reduces yields. All cartridges must be
installed with ink for printing and printer maintenance. For print quality, some ink remains in replaced
cartridges.
