Gap Sensing

This figure shows a Media Profile printout of a smart label where Gap/Mark Sensor is set to Gap in the
Sensors > Control menu.
In this example, the gap threshold value the printer selected (represented by the Gap/Mark dotted line) is
too close to the amplitude of the antenna pulse. This may cause the printer to falsely use the antenna as
the gap (top-of-form).
