Cleaning The Sensors - SATO CL408 Operator And Technical Reference Manual

5. View the Print Head Assembly from the front of the printer. Locate the two
mounting screws on the top of the assembly. They are accessible through the two
holes in the Top Assembly Plate. Unscrew these two screws and set them
aside.
6. The Print Head should now be loosened from the top of the assembly by grasping
either side and carefully pulling it forward.
7. Disconnect the signal and power cables from the print head connectors and set the
Print Head aside.
8. Carefully attach the new print head to the connectors, using caution to make sure
the connector keys are correctly positioned.
NOTE: Be careful not to scratch the printing surface of the print head while installing
it. Scratching the surface will cause permanent and irreparable damage and is not
covered by the warranty!
9. Locate the two mounting screws in the top plate assembly and align them with the
tapped holes in the new print head.
10. Re-secure the print head by tightening the screws.

CLEANING THE 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 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.
Supplies Needed:
1. Turn the printer off and remove the power cable.
2. Open the Label Access Door.
