I will soon be switching over to Piezography Pro inks from my existing ink set, with the intermediate step of using Piezo Flush to clear out the existing inks. My 4800 currently has the Matt Black cartridge installed.
I will be using the glossy Piezography Pro inks at the start, and want to keep the option open of possibly using the matt ink (with the required black ink change) in the future.
At what point should I do the black ink change procedure to change over to the Photo Black cartridge? Should I install Piezo Flush in the Photo Black cartridge, run the black ink change, and then install Piezo Flush in the rest of the cartridges and do the Initial Fill to swap out the rest of the inks?
