摘要

In one embodiment, a method for introducing ink into an inkjet print cartridge having a printhead includes introducing ink into the cartridge at a first pressure sufficient to displace air from the printhead and then introducing ink into the cartridge at a second pressure less than the first pressure. In one embodiment, a method for refilling a used inkjet print cartridge having a printhead includes introducing ink into the cartridge at a first pressure sufficient to overcome surface tension forces within the cartridge to displace air from the printhead and then continuing to introduce ink into the cartridge but at a second pressure lower than the first pressure.
