SECTION V- MAINTENANCE AND TROUBLESHOOTING
The CLV Bar Code Scanner is essentially maintenance-free. This section will cover preventive maintenance measures such as
cleaning of the optical surfaces and the system self test. Error messages that can occur in the Parameterization, Reading, and
Percent Evaluation modes are also discussed here.
CLEANING OPTICAL SURFACES
Depending on the operating environment of the CLV (amount of dust, humidity, etc.), these optical surfaces should be cleaned on
a regular basis:
• CLV reading window
• Exit window of photoelectric switch, if applicable, and the surface of the reflector (follow sensor instructions)
CAUTION:
No aggressive scouring agents or solvents should be used. These can damage glass surface of reading window or
plastic surfaces.
CLV Reading Window
If the read quality of a consistently good bar code print is low, this could indicate that the CLV window is dirty. A soft, lint-free
cloth dampened with a mild water-soluble cleaning agent is recommended for cleaning. Do not use a scouring motion when
cleaning.
Exit Window of Photoelectric Switch
If an external hardware trigger such as a photoelectric switch is being used as a clocking method, the exit window of the sensor
should be cleaned according to the manufacturer’s instructions.
