Sensors > Control > Sensed Distance
This value represents the distance that was sensed between the TOF of one
label to the TOF of the next label upon successful calibration. It is a read-only
value.
Gapped media: the distance equals the physical label length plus one gap,
notch, or hole (trailing edge of one gap, notch, or hole to the trailing edge of
the next gap, notch, or hole).
Black mark media: the distance equals the leading edge of one black mark to
the leading edge of the next.
Setting Automatically calculated upon calibration.

Sensors > Control > Gap/Mark Thresh
This menu item sets a value that, when exceeded by the output of the media
sensor, is recognized by the printer as a gap (or black mark). Upon
calibration, the value displayed is equal to the gap/mark threshold value set
by the procedure. If running the procedure does not provide a reliable
Top-Of-Form detection (e.g., when using unusual media), the Gap/Mark
Thresh value can be manually set to the desired value.

Sensors > Control > Paper Out Thresh
This menu item selects a value that, when exceeded by the output of the
media sensor, is recognized by the printer as a paper out condition. Upon
calibration, the value displayed is equal to the paper out threshold value set
by this procedure. If running the procedure does not provide a reliable paper
out detection, e.g., when using non-standard media, the Paper Out Thresh
value can be manually set to the desired value.
