Chapter 3 CALIBRATE CTRL
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.
Media Profile
This feature provides a graphical printout showing the relationship of the
Paper Out Threshold and the Gap/Mark Threshold. The profile printout
assists you in setting the thresholds for difficult media. This includes pre-
printed labels, and labels with poor gap/media dynamic range.
When selected, the printer will advance media and print the media profile
along the length of each label. The printer will continue to print the profile until
you press ↵.
The factory default is Print Profile.
Sensed Distance
This value (in inches) represents the distance that was sensed between the
TOF of one label to the TOF of the next label. With gapped media installed,
the distance equals the physical label length plus one gap, notch, or hole
(trailing edge of one gap, notch, or hole to the trailing edge of the next gap,
notch, or hole). With black mark media installed, the distance equals the
leading edge of one black mark to the leading edge of the next. This value is
automatically determined only after successful completion of Auto or Manual
Calibrate and cannot be changed manually.
The factory default is 0.00 inches.
Gap/Mark Thresh
This menu item sets a value that, when exceeded by the output of the media
sensor, is recognized by the printer as a gap (or black mark). When Auto or
Manual Paper Calibrate is performed, the value displayed is equal to the
gap/mark threshold value set by this procedure. If running the procedure does
not provide a reliable Top-Of-Form detection, e.g., when using unusual
media, the Gap/Mark Thresh value can be manually set to the desired value.
The range is 000-255, and the factory default is 171.
Paper Out Thresh
This menu item selects a value that, when exceeded by the output of the
media sensor, is recognized by the printer as a paper out condition. When
Auto or Manual Calibrate is performed, the value displayed is equal to the
paper out threshold value set by this procedure. If running the procedure does
not provide a reliable paper out detection, e.g., when using non-standard
media, the Paper Out Thresh value can be manually set to the desired value.
The range is 000-255, and the factory default is 136.
