Abstract

Cette invention concerne une cartouche d’encre remplaçable à pression constante ainsi que son procédé d’utilisation. L’extrémité avant du réservoir d’encre est constituée d’une entrée d’encre usagée et de deux ouvertures ou plus. L’extrémité arrière est ouverte, et une plaque de guidage des cartouches, ainsi qu’une cartouche d’encre usagée, sont présentes à l’intérieur du réservoir d’encre. Deux cartouches d’encre ou plus fournissent de l’encre à pression constante et sont fixées de manière amovible au réservoir d’encre ; une cartouche d’encre usagée qui contient l’encre usagée est également fixée de manière amovible au réservoir d’encre. Au moins une partie de chaque cartouche d’encre et une partie de la cartouche d’encre usagée sont respectivement situées à la partie arrière supérieure du réservoir d’encre. Pendant le montage, mettre tout d’abord le réservoir d’encre en place, puis insérer les cartouches d’encre et la cartouche d’encre usagée dans le réservoir d’encre. Alternativement, insérer tout d’abord dans le réservoir d’encre la cartouche d’encre qui n’interfère pas avec une tige de blocage, puis insérer le réservoir d’encre dans un compartiment pour imprimante, et insérer les autres cartouches d'encre et la cartouche d'encre usagée dans le réservoir d'encre. Le démontage peut se faire dans l’ordre inverse. La présente invention permet d’améliorer la capacité d’encre sans augmenter le profil de travail maximum de l’imprimante, et permet de diminuer la perte de fatigue de l’imprimante.
