  • Ink supplying apparatus and recording apparatus
    Publication number: 20050062815
    Abstract: Ink in a subtank is sent to an ink circulation path via an ink supply path, and is further returned from the ink circulation path to the subtank via an ink return path. Moreover, the ink is sent from a main tank to the subtank and returned to the main tank from the subtank. Because the ink is circulated not only between the subtank and recording heads but also between the main tank and the subtank, the ink is stably supplied to the recording heads.
