I have a 4800 that’s new to me. It’s configured with OEM inks (MK) but the MK is reading empty. Since its registering as an empty cart I can’t get to the normal menu with out replacing it. What’s the best way to dump the ink set that’s in there and load a PK InkThrift set of dye inks given that I don’t have a working MK cart to put in there to start with. If it helps, I do have an new empty MK cart from the IJM set that I bought but I have no plans to use MK ink and didn’t buy any.
