Abstract
An ink flow passage 7f is formed from an ink storage chamber of an ink cartridge 7 to an ink supply port. A passage control system 7j is located in the ink flow passage. The passage control system is capable of opening and closing the ink flow passage when receiving a drive force from an actuator 32. Particularly, air bubbles A1 staying on a filter member 22 within an ink supplying needle 21 is effectively discharged to a capping system 9 in a manner that a negative pressure is accumulated in an inner space of the capping system 9 in a state that the passage control system 7j is placed to a valve closing state. The passage control system 7j is provided in the ink cartridge. Accordingly, every time the ink cartridge is exchanged with a new one, the passage control system 7j is also exchanged with a new one. Accordingly, the printing function restoring operation performed through a cleaning operation based on the negative pressure accumulation is improved in reliability.
