Preparation:
Transparent sensor:
1. Peel off labels from the liner.
2. Open the “SA Cover” and put the media so that it is located on the platen roller and
both “SA Adjust Sensor L” (reflective sensor) and “SA Adjust Sensor U” (transparent
sensor).
If the media has a black mark, keep away the black mark from both sensors.
3. Close the “SA Cover”.
Reflective sensor:
1. Open the “SA Cover” and put the label media so that it is located on the platen roller
and the “SA Adjust Sensor L” (reflective sensor).
Keep away the black mark from the reflective sensor.
2. Close the “SA Cover”.
Sensor Adjustment Procedure (in common):
1. Turn on the power while pressing and holding the [PAUSE], [FEED] and [STOP] keys.
