Abstract A device for holding cartridges (32) from an ink-jet printer and keeping them supplied with ink comprises a container (10) divided into two chambers. The lower chamber (20) is filled with ink and the upper chamber (22) contains a seat (29,30) for housing one or more used cartridges (32). The cartridges (32) are automatically supplied with new ink drawn from the lower chamber (20) by means of porous elements (26) having a capillary structure, which are immersed in the ink and communicate with the cartridges (32) by means of a hole (54) in one of their walls (33).
