INTRODUCING INK INTO AN INK CARTRIDGE

摘要

In one embodiment, a method for introducing ink into an inkjet print cartridge (10 or 60) having a printhead (12 or 62) includes introducing ink into the cartridge (10 or 60) at a first pressure sufficient to displace air from the printhead (12 or 62) and then introducing ink into the cartridge (10 or 60) at a second pressure less than the first pressure. In one embodiment, a method for refilling a used inkjet print cartridge (10 or 60) having a printhead (12 or 62) includes introducing ink into the cartridge (10 or 60) at a first pressure sufficient to overcome surface tension forces within the cartridge (10 or 60) to displace air from the printhead (12 or 62) and then continuing to introduce ink into the cartridge (10 or 60) but at a second pressure lower than the first pressure.
