The present invention relates to a novel ink-jet cartridge for use in an ink-jet printer. The cartridge comprises an ink withdrawal port in which is placed a wick defining a capillary passageway to permit the transfer of fluid from the cartridge toward a withdrawal needle of the printer that is received in the withdrawal port. The capillary passageway promotes liquid transfer toward the withdrawal needle while, at the same time, forming a filter to prevent impurities from reaching the needle inlet orifices. An additional benefit of this construction is the ability of the capillary passageway to prevent the transmission of air bubbles, thus limiting the probability of air being sucked by the withdrawal nozzle when the cartridge is nearly depleted.
