Explanation
1
OK (Mid.)
Print position is detectable with the media sensor.
Threshold is at the midpoint between the peak and the
baseline.
2
OK (High)
Threshold is near the peak voltage, so detection of a
gap/black mark may fail if the difference between the
threshold and the peak voltage is very small. (Adjusting
the threshold to the midpoint between the peak and the
baseline enables more accurate detection.)
3
OK (Low)
Threshold is near the baseline voltage, so detection of
a gap/black mark may fail if the difference between the
threshold and the base voltage is very small. (Adjusting
the threshold to the midpoint between the peak and the
baseline enables more accurate detection.)
4
NG (1)
Print position is not detectable with the media sensor.
Fine adjustment is necessary.
5
NG (1)
Print position is not detectable with the media sensor
because the threshold  Baseline. Fine adjustment is
necessary.
6
NG (2)
Print position is not detectable with the media sensor.
(Calibration may enable print position detection, but it is
very difficult.)
