ABSTRACT:
A printing apparatus to form an image on a recording medium is provided. The printing apparatus includes a recording head, an ink cartridge, which contains the ink therein, an ink cartridge storage to store the ink cartridge, an ink conveyer tube, which connects the recording head and the ink cartridge to convey the ink, and a maintenance system having an aspirator to aspirate the ink to be drawn in the recording head and the ink conveyer tube and a cap to cover a nozzle surface of the recording head, and a releasing system, which is arranged in the ink conveyer tube to switch an open state and a closed state. The releasing system is arranged in a position higher than a position of the ink cartridge so that the releasing system and the ink cartridge have a predetermined water head difference therebetween.
