Abstract
(EN)
An ink jet cartridge (100) comprising an ink container (105) which comprises a bottom portion (110) and an upper portion (120), said bottom portion (110) being in communication with the printhead (135) through an ink supply port (130), and said upper portion (120) being in communication with a vent hole (140), wherein said bottom portion (110) comprises a first ink absorbing member (150), and said upper portion (120) comprises a second ink absorbing member (160), wherein said first ink absorbing member (150) is a compressible porous material and said second ink absorbing member (160) is an incompressible porous material, and wherein the capillarity of said first ink absorbing member (150) is higher than the capillarity of said second ink absorbing member (160).

(FR)
L'invention concerne une cartouche à jet d'encre (100) comprenant un réservoir d'encre (105) qui comprend une partie inférieure (110) et une partie supérieure (120), ladite partie inférieure (110) étant en communication avec la tête d'impression (135) grâce à un port d'alimentation d'encre (130), et ladite partie supérieure (120) étant en communication avec un orifice d'aération (140), ladite partie inférieure (110) comprenant un premier élément d'absorption d'encre (150), et ladite partie supérieure (120) comprenant un second élément d'absorption d'encre (160), ledit premier élément d'absorption d'encre (150) étant un matériau poreux compressible et ledit second élément d'absorption d'encre (160) étant un matériau poreux incompressible, et la capillarité dudit premier élément d'absorption d'encre (150) étant supérieure à la capillarité dudit second élément d'absorption d'encre (160).
