This test aims to determine the sensitivity of the label paper sensor after the printer is turned on.
When the user installs a new paper roll of a different specification or initializes the printer and
restores it to the factory default value, the label paper gap sensor needs to be re-measured. The
gap detection or black line mark calibration will be completed with your last set value as the
reference value. The default value of this printer sensor is set to gap calibration.
