Sensors > Calibrate - Printronix Auto ID T800 Series Administrator's Manual

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). Upon
calibration, the value displayed is equal to the gap/mark threshold value set
by the 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.

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. Upon
calibration, 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.

You can run Auto Calibration from the Home screen, this section, or the Tools > Print Tests > Run Test
menu. Upon execution, 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 if
successful. This process takes a few seconds to complete and results in changes to the values the printer
uses in the Sensors > Control subsection for Gap/Mark Threshold, Paper Out Threshold, and Sensed
Distance. These value changes take effect immediately within the current configuration menu.
