SET GAP
Description
This setting is used to set the gap sensor emission sensitivity. The printer initiates
automatic gap sensor calibration as you hold down the PAUSE key and then turn on
the printer power. But this function may cease to work if the thickness of the
backing paper and that of label with backing paper are not of appreciable difference
to the sensor, or when there are pre-printed marks or patterns on the label. In such
case, users have to calibrate the gap sensor manually by this command. This is a
trial-and-error method to attain the proper setting.
This setting will be saved in printer memory when turning off the power.
