PURPOSE:To perform not only the simplification of a waste ink port and a waste ink tube but also the equal distribution of waste ink to a cartridge, by guiding waste ink being a mixture of multiple color inks to a waste-ink branching apparatus having a mesh material or a porous material and further guiding the same to the waste ink tank provided to color cartridge from said waste-ink branching apparatus. CONSTITUTION:Waste ink being a mixture of multiple color inks is guided to a waste- ink branching apparatus 40 having a mesh material or a porous material and further guided to the waste-ink tank provided to each color cartridge from said branching apparatus 40. The waste-ink branching apparatus 40 is provided with one waste-ink port and an ink-receiving plate 41 provided with a large number of holes to the inlet of the waste ink flowed in through one communication tube and the mesh or porous material 42 and branched ports 431, 432, 433, 434 to cartridges are provided under said ink-receiving plate 41. By this constitution, the waste ink is infiltrated in the mesh or porous material to be spread to the entire surface thereof an uniformly distributed throughout the mesh or porous material and the ink saturated in each part falls to each branched port and, as a result, the distribution of the waste ink is performed. |
