to pin 3.
If the temperature of the “SA Head” exceeds 100
C (212
F), the head temperature sensor
output voltage becomes lower than the reference voltage, and pin 1 of U7A goes to “Low” level.
At this time, pin K1 (nTMPERR) is “Low” and the FPGA (U5) detects an abnormally high
temperature.
In this abnormal state, the printer stops +24V DC supply to the “SA Head”. Also it stops +24V
DC supply to the “SA PF Motor” and “SA Ribbon Motor F”.

PF motor temperature sensor
The PF motor temperature sensor is used to detect the temperature of the “SA PF Motor”. This
sensor is a thermistor bonded to the “SA PF Motor”.
Since the resistance of the thermistor changes according to the temperature change, the
voltage at pin 97 (TMPPF) of the CPU (U1A) changes accordingly. The CPU senses the
voltage at pin 97 (TMPPF) to detect the temperature of the “SA PF Motor”.
Printing operation when the “SA PF Motor” temperature rises:
When the temperature of the “SA PF Motor” rises to 95
C (203
F), printing speed is reduced to
avoid overheating. If it reaches 105°C (221°F), the “SA PF Motor” stops after printing the
current label. In this case, the LED on the operation panel blinks in red and the LCD displays
“Error PFMotor Hot”, and the printer goes off-line.
When the temperature of the “SA PF Motor” falls below 90
C (194
F), the LED and LCD
returns to normal display, and printing automatically resumes.
