A replaceable ink container (12) for providing ink to a printhead (24) of a printing system (10). The ink container has a housing (14) that includes and ink reservoir (16) for containing a supply of ink (18), and an ink level sensor (52) for sensing a low ink condition in the ink reservoir. The ink reservoir includes a capillary ink storage member (20). The ink level sensor includes resistance probes (48, 50) that are in fluid communication with the supply of ink, but are free from contact with the capillary ink storage member. The resistance probes are mounted to the housing by way of sensor ports (58, 60) that extend through the housing and prevent contact between the capillary ink storage member and the probes. The resistance probes protrude slightly from an exterior surface (62) of the housing to define electrical contacts for engaging corresponding electrical contacts (36) of the printing system. A change in electrical resistance measured across the resistance probes indicates a low ink condition in the ink reservoir <IMAGE>
