<p>A method of filling ink into a dual chamber ink-jet cartridge (A)for used with an ink-jet printer includes applying a vacuum to the cartridge (A) through a fill hole (52) of the cartridge (A) to substantially eliminate air within an ink absorbing member (40)_ of the cartridge (A). The fill hole (52) is sealed and then ink is pressure filled into the cartridge (A) through the fill hole (52). A vacuum is again applied to the cartridge (A) to substantially eliminate any residual air in the cartridge (A) due to the pressure filling of the ink. The fill hole (52) may be positioned over a free ink chamber (24) or over the ink absorbing member (40) of the cartridge. The vacuum includes applying a negative pressure of about 27.in/Hg. The negative pressure is applied at a cyc le rate of 5-30 seconds.</p> |
