PURPOSE:To prevent burnt magnet coil and missing dots, by always detecting the temperature of a dot type head and making the cooling operation according to the detected temperature. CONSTITUTION:A print hea 10 is provided with a vent 13 and a thermal sensor 12. The output of the thermal sensor is fed to a microprocessor of a printer control section. According to the combination of the output of each thermal sensor, the processor controls the operation of a printer with the relation of the instruction of the upper rank device. For example, assuming the average temperature of the sensor as T, when T1<=T<T2, and when line feed is made on the bas is of the line feed command, the normal end status is not immediately fed to the upper rank device and the normal end status is fed after the prescribed print head pause time. |
