Abstract
A liquid dispensing apparatus includes a mounting unit on which a liquid discharging device is mounted, a driving circuit to supply driving voltages to an actuator of the liquid discharging device mounted on the mounting unit, a capacitance measuring circuit configured to measure a capacitance value of the actuator and a controller configured to acquire the capacitance value, compare the capacitance value to a predetermined threshold value, and determine whether to supply a first control signal to the driving circuit to drive the actuator of the liquid discharging device to discharge a liquid based on the comparison of the capacitance value to the predetermined threshold value.
