Gap/Mark Sensor
Specifies the sensor type needed for detecting the top-of-form
position on media with label length indicators (gaps, notches, holes,
or black marks).
Disable. Select when using media with no label length
indicators (no gaps, notches, holes, or black marks), or
when
you want the printer to ignore all existing label length indicators
on the installed media.
NOTE: When you select Disable, the length of each label is based
on the Label Length value entered.
Mark. Select when using media that has horizontal black marks
located on the underside of the label liner or tag stock. The
top-of-form position is the leading edge of the black mark.
Gap. Select
when using media with a liner space between
die cut labels or when using tag stock with notches or holes as
label length indicators on white background media. The
top-of-form position is the leading edge of the die cut label
(trailing edge of the gap, notch, or hole).
Advanced Gap. Select when using media that has liner gaps
between die cut labels with black background. The top-of-form
position is the leading edge of the die cut label (trailing edge of
the gap, notch, or hole).
Advanced Notch. Select when using media with notches or
holes that interrupt a black vertical line on the underside of the
media. The top-of-form position is the leading edge of the die
cut label (trailing edge of the gap, notch, or hole).
The default is Disable.
Gap Sensing for Smart Labels
If your smart labels have a horizontal black bar located within each
liner gap, set Gap/Mark Sensor to Gap. When you examine a
Media Profile printout (page 32), you will see that the black bar
provides a much higher amplitude pulse than that of any antenna,
which will provide excellent top-of-form reliability.
