CALIBRATE CTRL
Use Label Length
Determines whether or not the Label Length value set in the QUICK SETUP
or MEDIA CONTROL menu is used during Auto Calibrate.
•
Enable
. The Label Length value set in the QUICK SETUP or MEDIA
CONTROL menu 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 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. Example: A 0.2 inch calibrated
Sensed Distance with a 3.0 inch long label installed.
NOTE:
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.
•
Disable
.
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 factory default is Enable.
NOTE:
Although the “Use Label Length” keeps its value (enable/disable) at
all times, it will always be disabled when “Set Label Length” is set to
“Automatic”. The correct setting will take effect when “Set Label
Length” is set to manual. Based on the setting on the “Set Label
Length” menu in the Media Control menu, the “Use Label Length”
menu will be ignored (disabled).
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:
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.
The range is: 5% to 95% in 5% increments
The factory default is 50%.
