3.4.2 Positioning of full size gap sensor

The unit is equipped with a full size gap sensor. From the minimum label width (25,4 mm) to the
maximum the sensor can be moved to the wanted position.
As shown on the pictures below, the sensor can be moved in two parts – the lower side and the
upper side. Both should match so the beam can run from the diode to the transistor! If that is
not adjusted properly the sensor can not work!
