A method of refilling an ink bag that is used in an ink jet recorder, the ink bag is initially filled with ink through an opening in the bag, and is sealed after the ink bag is initially filled. The method comprises the steps of removing the ink bag from the ink jet recorder, positioning the ink bag, inserting an ink needle into a separate opening in the ink bag that is different than the first opening through which the ink bag is initially filled with ink, discharging ink from the ink bag through the second opening, and charging the ink bag through the second opening with a specified quantity of ink.

Method of refilling an ink cartridge for use in ink jet recorder

A method of manufacturing an ink cartridge for use in an ink jet recorder, comprising the step of providing an ink bag having a top end, and a bottom end below the top end, the top end being open and the bottom end having an ink feed port therein; moving the ink bag from a first position near a top edge thereof and positioning the ink bag in a vacuum chamber; depressurizing the vacuum chamber; charging a selected quantity of ink into the ink bag; sealing the open end of the ink bag at a second position below the first position; pressing the sealed portion of the ink bag to a selected thickness with press plates; sealing the bag in the pressed position at a third position below the second position; and cutting the ink bag between the second and third positions.

Method of manufacturing an ink cartridge for use in ink-jet recorder

A method of refilling an ink bag of an ink cartridge for use in an ink-jet recorder. The method includes first removing the ink cartridge and ink bag from the ink-jet recorder. The ink bag may then be refilled by positioning the ink bag on a surface, inserting an ink needle into a port of the ink bag, and by discharging ink from the ink bag and charging the ink bag with a specified quantity of ink.

The entire part of a rear surface 2 of a nozzle plate 1 excluding peripheral portions 6 of nozzle holes 4 is coated with a resist tape, and this nozzle plate 1 is immersed in an electrolytic solution in which ions of a metal and particles of a water-repellent resin are dispersed to provide a plating thereon, and the plated nozzle plate 1 in the electrolytic solution is then heated to a temperature that is higher than a melting point of the water-repellent resin, whereby an entire portion extending from a front surface 3 of the nozzle plate 1 and the nozzle holes 4 contiguous to the front surface to the rear surface 2 is provided with a eutectoid plating layer 8 to suppress deviation of the passage of ink droplets due to wetting by an ink or the like.
