Run 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
preprinted 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
↵.
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
trailing edge of one black mark to the trailing 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 to 255. The factory default value depends on the value set in
the Gap/Mark Sensor option (in the SENSOR SETUP menu).
NOTE: If Gap/Mark Sensor (in SENSOR SETUP menu) is set for Gap
sensing, the factory default is 140. If Gap/Mark Sensor is set for
Mark, the factory default is 75.
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 to 255. The factory default value depends on the value set in
the Gap/Mark Sensor option (in the SENSOR SETUP menu).
NOTE: If Gap/Mark Sensor (in SENSOR SETUP menu) is set for Gap or
Disable sensing, the factory default is 190. If Gap/Mark Sensor is set
for Mark, the factory default is 150.
