Sensors > Calibrate > Use Label Length
Determines whether or not Media > Image > Label Length is used during
Auto Calibrate. This resolves problems where the sensor(s) may mistake
high noise levels or preprinted images within the label as the gap, notch,
hole, or black mark that could result in a sensed distance value much shorter
than the actual label length. For example, a 0.2 inch calibrated Sensed
Distance with a 3.0 inch long label installed.
Auto Calibrate relies exclusively in its ability to detect
varying transitions between labels and gaps, notches,
holes, or black marks while advancing media during
the calibrate process to determine Sensed Distance.
The amount of media advanced is based on the
number of transitions detected.
The Label Length is used in the calibrate algorithm.
This causes the Auto Calibrate process to advance
media the minimum distance required to detect the
true gap, notch, hole, or black mark used for TOF
(Top-of-Form) sensing.
This menu will be ignored when Media > Image
>Set Label Length is set to “Automatic”. This is
the Factory default.
Setting the Label Length value less than half the
actual length of the label in use will result in
erroneous Sensed Distance values when Auto
Calibrate is performed.
