ABSTRACT:
An ink refilling method for refilling the ink into an ink cartridge comprising an ink guiding member and an ink absorbing member, includes the following steps of preparing an ink refilling apparatus for refilling the ink into the ink absorbing member disposed within the ink storing portion of the ink cartridge, through an ink guiding member, wherein an ink refilling apparatus includes a refill ink storing portion for storing the refill ink; an air ventilating portion for allowing communication between the refill ink storing portion and the atmospheric air; a sealing member for sealing the air ventilating portion; an ink injecting portion to be inserted into the ink delivery port portion of the ink cartridge; an opening portion for guiding the ink out of the refill ink storing portion, being provided on the ink injecting portion; and a pressure generating device for increasing the internal pressure of the refill ink storing portion; inserting the ink injecting portion of the ink refilling apparatus into the ink delivery port portion of the ink cartridge; breaking the meniscus formed at the opening portion of the ink refilling apparatus with the use of the pressure generating device, so that the ink within the refill ink storing portion of the ink refilling apparatus is guided toward the ink guiding material of the ink cartridge; and removing the sealing member covering the air ventilation portion, so that the ink can naturally descend into the ink storing portion of the ink cartridge.
