Abstract
A joint section of a fill device is coupled to a supply opening of an ink cartridge, and a pressing force section presses an inside plug of the ink cartridge into the supply opening, to press down the inside plug against a biasing unit and release an opening to connect an ink fill section with an ink container. A first pump is operated and fills ink to the inside of the ink container. After the filling, the joint section separates from the supply opening, and the inside plug seals the supply opening by the biasing unit. Ink is filled with no spilling, into the ink container having an ink supply section with valve, and the ink cartridge can be manufactured with good efficiency.
