Figure 1. Media Profile Printout
Gap Sensing
This figure shows a Media Profile printout of a smart label where Gap/Mark
Sensor is set to 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 amplitude of the antenna pulse.
This may cause the printer to falsely use the antenna as the gap (top-of-form).
