Abstract:
A head element operation check mechanism in a printer which is provided with a head including a plurality of head elements is provided. A controller controls a selector to selectively and electrically connect a resistor element provided in each of the head elements to a test resistor element in series. A test power source applies a test voltage to a serial circuit of the test resistor element and the resistor element. A divided voltage measuring unit measures a divided voltage of the serial circuit of the test resister element and the resistor element in response to control of the controller.
