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.

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.

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).

Disable (factory default). Run Auto-Cal 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.

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 Setup menu, the “Use Label Length”
menu will be ignored (disabled).

•
Enable. The Label Length value set in the MEDIA SETUP menu is used
in the calibrate algorithm. This causes the Run Auto-Cal 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.
