label in use will result in erroneous Sensed Distance values when
Run Auto-Cal is performed.

Threshold Range
This option allows the user to select the optimal threshold range for the label
stock in use. The printer defaults to using a threshold range of 50% of the
positive going pulse (see Media Profile) that represents each gap, notch or
mark detected after doing an Auto or Manual Calibrate. The printer then
detects anything within the label with that threshold range as TOF. While this
range is ideal for most medias, some labels with a preprinted image, liner gap
or inlay can confuse the media sensor(s) causing a false TOF detection. In
most cases this can be resolved by selecting a higher threshold range so the
printer will only trigger on the true TOF (gap, notch or mark) position.

NOTE: Set the label length value in the Media Setup menu to the actual
length of the installed labels. A new threshold range will not take
affect until an Auto or Manual Calibrate is successfully performed. A
Media Profile should be run after a Calibrate to visually verify that the
new range is the best possible selection.

Mark TOF Detect
NOTE: This option applies only when Gap/Mark Sensor is set to Mark.
Allows the user to select which edge of the black line is used for TOF (Top Of
Form). The leading edge refers to the first edge seen by the media sensor as
the media feeds out of the printer or the start of the black line.
