Abstract
A method for refilling ink into ink cartridge comprises: I. hermetically connecting an ink injection port of the ink cartridge to an ink supply port of an ink storage container of an ink filling tool which is not completely filled with ink, connecting a suction unit to the ink storage container of the ink filling tool and sealing the ink cartridge; II. sucking out the air inside the ink storage container of the ink filling tool by the suction unit; III. releasing the suction unit so that the ink inside the ink storage container of the ink filling tool is automatically absorbed by the ink cartridge due to atmospheric pressure balance. An ink filling tool used in the method described above also is provided.
