<p>A head element operation check mechanism in a printer which is provided with a head including a plurality of head elements (3) is provided. A controller (10) controls a selector (5,7) to selectively and electrically connect a resistor element provided in each of the head elements to a test resistor element (R4) in series. A test power source applies a test voltage (VDD) 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.</p> |
