摘要： A bubble removing apparatus for removing air bubbles in ink to be supplied to a printer head of an inkjet printer and a method of removing the air bubbles are provided to provide a smooth flow of ink to the inkjet printer head. When an air bubble removing operation is performed, ink in an ink tank is moved towards the printer head through a filter unit by operating the pump in a forward direction, and the ink that has moved towards the printer head is returned to the ink tank through the filter unit by operating the pump in a reverse direction. Air bubbles trapped in the filter unit are moved to the ink tank due to the operation of the pump in the reverse direction and are removed in the ink tank by the gravitational force, and thereby a smooth flowing ink supply can be provided to the printer head.

摘要： An ink cartridge easily attached to and removed from an inkjet printer and an ink circulation system of the inkjet printer. The ink cartridge includes a plurality of print heads ejecting ink, an ink channel unit supplying ink to the plurality of print heads, at least one filter unit filtering ink supplied to the ink channel unit, and at least one septum unit connecting the ink channel unit, at least one filter unit, and the inkjet printer. The ink circulation system includes the ink cartridge, an ink tank storing ink to be supplied to the ink cartridge, at least one 3-way valve interposed between the ink cartridge and the ink tank to selectively control channel circulation and priming circulation, the channel circulation circulating ink in the ink channel unit and the priming circulation circulating ink in the at least one filter unit, and an ink pump interposed between the at least one 3-way valve and the ink tank for providing driving power for circulating ink.
