Advanced Gap Sensing
This figure shows a Media Profile printout of a smart label where Gap/Mark
Sensor is set to Advanced Gap in the CALIBRATE CTRL menu.
In this example, the gap threshold value the printer selected (represented by
the Gap/Mark dotted line) is too close to the baseline (die cut label). If there is
an increase in noise or the opacity of the liner or ribbon, the printer may
falsely use the noise as the gap (top-of-form).
