2. Select the transparent sensor, and open the sensor arm.
3. Install only the liner media (label backing paper) with the label
media removed so that it will pass between the platen roller and
the media sensor. (Be careful that media with black marks does
not pass the media sensor.) Then close the sensor arm and the
printhead.
4. If the PAUSE key is pressed and released while the MODE/
REPEAT key is pressed, the PRINT LED goes off, after the
CONDITION LED switches from lit to rapid flashing, media
feeding starts, and the sensor is automatically adjusted.
5. If automatic adjustment stops normally, the PRINT LED and
CONDITION LED return to their original status. If it stops
abnormally (adjustment impossible), the CONDITION LED and
ERROR LED flash.
6. If the STOP key is pushed, it exits sensor adjustment mode.
