I had a mind to do that a few years back. Used the "starter" cartridge until it said empty - but still seemed to have plenty of toner, also have a couple of replacement cartridges.
My intention was to copy the chips on the two replacement cartridges to see if they had different data (so that the printer would know if you merely reset the chip to the new values on the same cartridge) as well as the "empty" one and start by telling the empty one it was actually full to see how far it would go.
Never got around to it, shelved the printer for the time being.
