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.
Auto Calibrate can also be initiated from the TEST PRINT key, the
CALIBRATE CTRL menu, or the DIAGNOSTIC menu. Press the
"Auto Calibrate" displayed. The printer will then advance media the distance
needed to accurately detect the label length indicators, then stop at the Top-
of-Form position and momentarily display the Sensed Distance. The process
takes a few seconds to complete. The end result will be a change to the Gap/
Mark Threshold, Paper Out Threshold, and Sensed Distance values that the
printer will use. The changes in values 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.
