Abstract: 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.

Abstract: In one embodiment, a method for introducing ink into an ink cartridge includes introducing ink into an ink holding chamber through ink ejection nozzles and, simultaneously with introducing ink into the ink holding chamber through the ink ejection nozzles, introducing ink into the ink holding chamber through an opening other than the ink ejection nozzles or applying a negative pressure at a first opening to the ink holding chamber and applying a positive pressure at a second opening to the ink holding chamber. In another embodiment, a method includes performing a primary operation on an ink holding chamber by introducing ink into the ink holding chamber through ink ejection nozzles and performing a secondary operation on the ink holding chamber to increase the flow of ink to a distal part of the ink holding chamber relative to the flow of ink to a proximal part of the ink holding chamber.

Abstract: In one embodiment, a method for refilling a used ink cartridge includes determining a quantity of ink remaining in an ink holding chamber in the cartridge, determining a desired quantity of ink to refill the chamber based on a difference between a capacity of the chamber and the quantity of ink remaining in the chamber, and refilling the chamber with the desired quantity of ink. In another embodiment, a method for refilling a used ink cartridge includes introducing ink into an ink holding chamber in the cartridge, simultaneously with introducing ink into the chamber, monitoring the level of ink in the chamber, and ending the introduction of ink into the chamber when the level of ink in the chamber reaches a desired level.
