Cal in Peel Mode
This option allows you to perform a calibration (Run Auto-Cal or Pwr Up
Auto-Cal) in Peel-Off Media Handling mode.
•
Disable (factory default). 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.
•
Enable. Run Auto-Cal 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
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. The factory default is 20.

peeled labels. Therefore, be prepared to remove the labels as they
are automatically peeled.
