Cal in Peel Mode
This option allows you to perform a calibration (Auto Calibrate or Pwr Up
Auto-Cal) in Peel-Off Media Handling mode.
•
Enable. Auto Calibrate can be performed from the front panel, and if the
Pwr Up Auto-Cal option is enabled, calibration will be performed at power
up.
NOTE: Calibration in Peel-Off mode does not stop and wait for you to remove
peeled labels. Therefore, be prepared to remove the labels as they
are automatically peeled.
•
Disable. The printer will not permit calibration and a
"CANNOT CALIBRATE/Disable Peel-Off" message will briefly display.
Additionally, if "Pwr Up Auto-Cal" is enabled, the printer will not perform
calibration at power up.
The factory default is Disable.
Min Calib Delta
Minimum Calibrate Delta changes the minimum threshold value the sensor(s)
require to detect the difference between the label and a gap, notch, hole or
black mark. This allows bolder gaps (such as notches or holes) to be used as
the TOF while intermediate gaps (liner) can be ignored. Increasing the Min
Calib Delta makes the sensor(s) less sensitive to intermediate gaps and
noise. Decreasing the Min Calib Delta makes the sensor(s) more sensitive for
detecting gaps on low contrast media, where there is very little difference
between the label and the gap (liner).
The range is 012 - 050.
NOTE: When Gap/Mark Sensor = Disable, Gap, or Mark, the default is 12.
When Gap/Mark Sensor = Advanced Gap or Advanced Notch, the
default is 20.
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.
