摘要：
A control section of each ink tank detects a difference in voltage value between a voltage value of an output data signal and a voltage value of an input data signal through the differential detector. When a plurality of ink tanks of the same color are mounted, this voltage difference carries a value different from a voltage of the original output data signal. Accordingly, by detecting this voltage difference, it can be detected that the plurality of the ink tanks of the same color are mounted, these ink tanks can be specified and identified, and be controlled individually.
