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.
You receive a message reading "Scanner
Communication Failure" when trying to
connect a 1551E or 1553 decoded
scanner.

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.
Make sure that:
• You are using the correct cable (P/N 3-606034-02).
• Try enabling the scanner port. Go to Data
Collection > Dock Tethered Scanner > Enable
Scanner Port.
• Try upgrading the scanner firmware.
• Select ASCII as the scanner model.
