An ink box detection system and method thereof are provided for detecting an ink box installed in an ink jet apparatus. The ink box has an identification circuit to generate a reference voltage. The detection system includes a voltage divider resistance with a power supply, a connector for connecting the identification circuit of the ink box and the voltage divider resistance with the power supply, a voltage supplier, a voltage detector connected to the connector and the voltage supplier, and a controller connected to the voltage supplier and the voltage detector. The voltage supplier provides an adjustable voltage that is adjusted by an adjustable digital signal from the controller. The voltage detector includes a single comparator for comparing the adjustable voltage with the reference voltage. When the adjustable voltage is the same as the reference voltage, a detection signal is outputted to the controller to identify the ink box.
