Cleaning the Label Edge Sensors
There are two sensors that are used to control the positioning of the label. One is a transmissive see-thru sensor
that detects the edge of the label by looking through the backing paper which is translucent and detecting the
presence of the opaque backing. The other is a reflective sensor that detects the light reflected from the bottom
of the label liner. When a printed black Eye-Mark passes through the beam, the light is no longer reflected back
to the sensor detector, indicating to the printer that it should use this position as the start of a new label. When
dust, dirt or other foreign matter interferes with the light path of either of these sensors, the results is erratic
label positioning. These sensors should be cleaned regularly, at least every two rolls of labels. They are both
located on an adjustable assembly in the throat of the printer between the Label Hold Down and the Print Head.
