ABSTRACT:
A method of filling ink into a dual chamber ink-jet cartridge for use with an ink-jet printer includes applying a vacuum to the cartridge through a fill hole of the cartridge to substantially eliminate air within an ink absorbing member of the cartridge. The fill hole is sealed and then ink is pressure filled into the cartridge through the fill hole. A vacuum is again applied to the cartridge to substantially eliminate any residual air in the cartridge due to the pressure filling of the ink. The fill hole may be positioned over a free ink chamber or over the ink absorbing member of the cartridge. The vacuum includes applying a negative pressure of about 27.5 in/Hg. The negative pressure is applied at a cycle rate of 5-30 seconds.
