ABSTRACT:
Embodiments provide a method of refilling an inkjet printer cartridge. The method includes providing an inkjet printer cartridge and lowering the pressure surrounding the cartridge below atmospheric level. A first volume of ink is directed into the cartridge at the reduced pressure. The method further includes at least partially raising the pressure surrounding the cartridge and subsequently at least partially lowering the pressure surrounding the cartridge. A second volume of ink is then directed into the cartridge at the second reduced pressure.
