This motor feeds media. A thermistor is attached to the motor to
detect the motor temperature.
It consists of a head driver and thermal elements. The 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 photointerrupter to detect the print head
position; up or down.
This sensor is a photo sensor to detect a label stuck on liner or
U-shaped notches on tag. It also detects the media end.
This sensor is a photo sensor to detect a black mark on tag. It
also detects the media end
It controls entire printer system.
It is a relay PCB located between the "SA Main PCB" and the
"Unit Mechanism". The optional auto cutter unit or the peeler unit
is connected to this PCB.
It consists of LCD, LED and switches for operation.
It converts AC input to DC24 V.
