Reflective Sensor
This motor feeds media. A thermistor is attached to this motor to detect
the motor temperature.
This sensor is a mechanical switch to detect the print head position; up
or down.
Consists of the transparent sensor and the reflective sensor that move
to right and left simultaneously by turning the adjust sensor position
knob. Together with the reflective sensor, it is used to detect a label
stuck on liner or a U-shaped notch on tag. The reflective sensor alone
is used to detect the black marks on tag. The media end is detected
with these sensors.
