Unlike Europe and China region SureColor printers, the North American region printers have been designed by EPSON® to not work with non-EPSON branded cartridges. We now have solutions for the North American region Epson SureColor P400, P600 and P800 printers. The Epson SC P6000, P7000, P8000, P9000, P10000, P20000 cartridge solutions are not something we are currently selling, but we are aware that others are. We're waiting for a more supportable solution. Refrain from ever updating firmware on any of these North American region printers.
