A PF Motor
This motor feeds media. A thermistor is attached to the side surface of this
motor to detect the motor temperature.
This switch is a mechanical lever switch to detect the print head position;
up or down.
This sensor is a photo sensor to detect the labels stuck on liner or
U-shaped notches on tag. It also detects the media end.
This sensor is a photo sensor to detect the black marks on tag. It also
detects the media end.
It consists of a head driver and thermal elements. Thermal elements are
heated to make printing on media. The thermal head incorporates a
thermistor to detect the thermal head temperature.
This sensor is a photo sensor to detect a near end status of roll paper
installed.
