1-4. Adjustable Sensors
There are two media sensors; the upper sensor (transparent sensor) and the bottom sensor
(reflective sensor). Both upper sensor and bottom sensor are used to detect the labels on the liner
or the U-shaped notches of tag. The bottom sensor is used to detect the black marks on tag. Also,
both sensors are used to detect media end.
The mechanical adjustable ranges of sensors are as follows.
Upper sensor (transparent sensor): 2.8 to 60.8 mm (0.11 to 2.39")
Lower sensor (reflective sensor): -0.2 to 57.8 mm (-0.01 to 2.28")
Each sensor is adjustable independently. However, when you use the upper sensor (transparent
sensor), the lower sensor (reflective sensor) must be always used together so that they become a
set of sensors.
When both sensors are moved to the left end or the right end (center of the printing mechanism),
both sensors coincide for detecting a label or U-shaped notch.
For details about the media sensors, refer to "2-1-3 Label/Tag Detection Mechanism".
