the tapped holes in the new print head.
10. Re-secure the print head by tightening the screws.
CLEANING THE SENSORS CL608e and CL612e
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 label.
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.
