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.
Nouvelle cartouche à jet d'encre pour utilisation dans une imprimante. Elle comprend un orifice de retrait d'encre dans lequel est placée une mèche définissant un passage capillaire permettant le transfert d'un fluide depuis la cartouche vers une aiguille de retrait de l'imprimante qui est reçue dans l'orifice de retrait. Ce passage favorise le transfert du liquide vers l'aiguille de retrait, tout en formant un filtre pour empêcher que des impuretés n'atteignent les orifices d'entrée de l'aiguille. Un autre avantage de cette construction est la capacité du passage capillaire d'éviter la transmission de bulles d'air, limitant ainsi la possibilité que de l'air soit aspiré par la buse de retrait lorsque la cartouche est presque épuisée.
