2-1-3. Label/Tag Position Detection Mechanism
The major components of the label/tag position detection mechanism are:
(a) Adjustable Sensor (consisting of transparent sensor and reflective sensor)
(b) Front Fixed Sensor (consisting of transparent sensor and reflective sensor)
By default, the Sensor Select menu is set to “Rear Adj Sensor”, and the adjustable sensor is
selected.
The Adjustable Sensor consists of the reflective sensor (bottom sensor) and the transparent
sensor (upper sensor) as shown blow. The reflective sensor consists of 1 LED and 1
phototransistor, while the transparent sensor consists of 1 LED (in practice, LED is not a sensor
but it acts as a sensor by the combination of the reflective sensor’s phototransistor).
The following table shows how the sensors detect a label, U-shaped notch or black mark.
