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).
To avoid this problem, increase the Threshold Range value to 60% in the
CALIBRATE CTRL menu (the default is 50%), then run an Auto Calibrate
again (Cross-ref to Auto Calibrate).
NOTE: Any changes to Threshold Range will not take effect until you run an
Auto Calibrate again.
This will raise the Gap/Mark threshold high enough so that the printer will not
falsely use the antenna or noise as the gap (top-of-form).
