Problems While Scanning Bar Codes (continued)
Problem
The scanner will not read the bar
code label.
The scanner does not read the bar
code labels quickly, or the scanning
beam seems to be faint or obscured.
You scan 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.

Solution
Make sure you aim the scanner beam so it
•
crosses the entire bar code label in one pass.
The angle you are scanning the bar code label
•
may not be working well, or you may be
scanning the label "straight on." Try scanning
the bar code label again, but vary the scanning
angle.
The bar code label print quality may be poor
•
or unreadable. To check the quality of the bar
code label, try scanning a bar code label that
you know will scan. Compare the two bar
code labels to see if the bar code quality is too
low. You may need to replace the label that
you cannot scan.
Make sure the bar code symbology you are
•
scanning is enabled. Use the Configuration
Utility to check the symbologies. On the
Symbologies Menu, each symbology that is
enabled has a check mark ( ) next to the
name of the symbology. If your bar code
symbology is disabled, enable it and then try
scanning the bar code label again.
Make sure that the application you are
•
running on the computer is expecting input
from a bar code. You may need to type this
information instead of scanning it.
The scanner window may be dirty. Clean the
window with a solution of ammonia and water.
Wipe dry. Do not allow abrasive material to
touch the window.
The computer may have decoded the bar code
•
label in a symbology other than the label's
actual symbology. Try scanning the bar code
label again. Make sure you scan the entire
label.
To operate the computer quickly and
•
efficiently, you should enable only the bar
code symbologies that you are going to scan.
