I upgraded to a P800 a few months back, finally drained the ink carts to my old 4880. They are the high capacity carts that stick out from the printer. If you’d like them, I am happy to ship via UPS. I just ask you cover the shipping fees. I don’t check the forum often, so please email me at firstname.lastname@example.org. Includes all 9 carts and a spare magenta.
