Adjusting the Reflective sensor
1. The reflective sensor is selected.
2. With the reflective sensor selected, install the label media
so that it is between the platen roller and the media sensor.
Be careful that black mark and media gap do not pass the
media sensor.
 When using continuous media or label media with no gaps
Mount in such a way that the part without a black mark (in the case
of label media, this means the label paper portion) faces the platen
roller and the media sensor.

it faces the platen roller and media sensor. Avoid contact with black
mark.
