(3-4) Head temperature sensor
The head temperature sensor is used to detect the temperature of the thermal head. This
sensor is a thermistor incorporated in the Head SA. Since the resistance of the thermistor
changes according to the temperature change, the voltage at pin 7 (HDTMP) of IC1 (CPU)
changes accordingly. The CPU senses the voltage at pin 7 to detect the head temperature.
According to the temperature of the print head, the CPU controls the printing pulse width
applied to the thermal elements to keep the printing density constant.

Printing operation at the head temperature rise:
When the head temperature reaches 65
°
C (149
°
F), printing stops after printing the current
label. In this case, PRINT LED and CONDITION LED simultaneously blink on the
operation panel. When the temperature of the Head SA falls below 55
°
C (131
°
F), LEDs
stop blinking and printing resumes.
