Gap/Mark Sensor
The available options specify the sensor type needed for detecting the Top-of-
Form position on media with label length indicators (gaps, notches, holes, or
black marks).
•
Disable (the default). 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 in the MEDIA CONTROL menu or the
value sent via host software.
•
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).
Auto Calibrate
This feature is used to improve the sensitivity and reliability of the Media
Sensor in detecting gaps, notches, holes, or black marks on the installed
media, as well as a paper out condition.
You can initiate Auto Calibrate from the CALIBRATE CTRL menu or the
DIAGNOSTIC menu. When "Auto Calibrate" displays on the LCD, press the
key. The printer advances media the distance needed to accurately detect the
label length indicators, then stops at the Top-of-Form position, and
momentarily displays the Sensed Distance. This process takes a few seconds
to complete and results in changes to the values the printer uses for Gap/
Mark Threshold, Paper Out Threshold, and Sensed Distance. These value
changes take effect immediately within the current configuration menu.
Auto Calibrate is completed successfully when the Sensed Distance
displayed correctly matches that of the installed media. When Gap is
selected, the Sensed Distance should match the length from the trailing edge
of one gap to the trailing edge of the next gap (one label + one gap). When
Mark is selected, the Sensed Distance should match the length from the
leading edge of one black mark to the leading edge of the next black mark.
Auto Calibrate supports label lengths up to 24 inches.
