Chapter 5 — Troubleshoot and Maintain the Computer
60 Thor CV31 Vehicle-Mount Computer User Manual
The scanner or imager cannot
read the bar code.
Try these possible solutions:
• Position the scanner beam so that it
crosses the entire bar code label in
one pass. Try to vary the scanning
angle.
• Check the quality of the bar code
label. Scan a bar code label that you
know scans properly. Compare the
quality of the two bar code labels.
You may need to replace the label
that you cannot scan.
• Make sure the bar code symbology
is enabled and configured correctly.
Start Intermec Settings and go to
Data Collection > Symbologies for
the scanning device (scanner, virtual
wedge) to check and enable
symbologies.
• Make sure the computer application
is expecting input from a bar code.
You may need to type this
information instead.
• The scanner may not be turned on or
the scanner may be unable to scan
a specific bar code. Run the
ScanDiagnostic application.
The scanner or imager cannot
read the bar code quickly, or the
scanning beam seems to be
faint or obscured.
The scanner or imager window may be
dirty. Clean the window with a solution
of mild soap and water. Wipe dry. Do
not allow abrasive material to touch the
window.
You read a valid bar code label
to enter data for your
application. The data decoded
by the scan module does not
match the data encoded in the
bar code label.
The computer may have decoded the
bar code label in another symbology.
Scan the bar code label again. Make
sure you scan the entire label.
The input device attached to the
computer does not work well or
read bar code labels very
quickly.
Set the Scanner Model command to
the specific attached input device.
Enable only the bar code symbologies
being used.
