Further to the Multipurpose discussion, my Lexmark ran out of black ink yesterday and the cartridge sellers I rang tell me that Lexmark fill the initial cartridges to only half of their capacity.

I refilled the cartridge with ink specifically for Canon i560 printers and it works fine. I figure that if the print head fouls up I am only up for the amount of a new cartridge anyway as the cartridges carry the print head in them.
