摘要

In one embodiment, a method for refilling a used ink cartridge (10 or 60) includes determining a quantity of ink remaining in an ink holding chamber (14 or 64, 66 and 68) in the cartridge (10 or 60), determining a desired quantity of ink to refill the chamber (14 or 64, 66 and 68) based on a difference between a capacity of the chamber (14 or 64, 66 and 68) and the quantity of ink remaining in the chamber (14 or 64, 66 and 68), and refilling the chamber (14 or 64, 66 and 68) with the desired quantity of ink. In another embodiment, a method for refilling a used ink cartridge (10 or 60) includes introducing ink into an ink holding chamber (14 or 64, 66 and 68) in the cartridge (10 or 60), simultaneously with introducing ink into the chamber (14 or 64, 66 and 68), monitoring the level of ink in the chamber (14 or 64, 66 and 68), and ending the introduction of ink into the chamber (14 or 64, 66 and 68) when the level of ink in the chamber (14 or 64, 66 and 68) reaches a desired level.
