4.3.2 Gap/Black Mark Calibration, Self-test and Dump Mode
While calibrating the gap/black mark sensor, the printer will measure the label length

The calibration of the gap or black mark sensor depends on the sensor setting
last used.
Please follow the steps below to calibrate the sensor:
1. Turn off the power switch.
