Abstract

In a head diagnosis apparatus and the head diagnosis method for diagnosing the condition of a thermal head (1; 23), after measuring the resistance value of a plurality of heat generation resistive elements (93) arranged on a head surface of the thermal head, a change amount of the resistance value of each heat generation resistive element (93) is calculated on the basis of the resistance value of each heat generation resistive element (93) measured in the past and the resistance value of each heat generation resistive element (93) measured at the current time. An electrification state of each heat generation resistive element (93) is judged on the basis of the calculation result, and the thermal head (1; 23) is diagnosed to see whether it is good or bad in accordance with the determination result, thereby permitting the diagnosis on the condition of the thermal head (1; 23) before actually entering a printing stage.
