The scanner cannot read the bar
code.
• 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 the Settings app and check the
scanner settings to verify that
decoding is enabled for the symbology
you are using.
• Make sure the computer application is
expecting input from a bar code. You
may need to type this information
instead.
The scanner cannot read the bar
code quickly, or the scanning
beam seems to be faint or
obscured.
The scanner 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.
