Problems Reading 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.
When Enable Scanner Port is
checked in Intermec Settings, the
"COM port is busy. Another
application may be using the
port" error message appears.
The scanner does not read the bar
code or is corrupted when it is
enabled as an ASCII scanner.
You scan a valid bar code label to
enter data for your application.
The data decoded by the scanner
does not match the data encoded
DRAFT
in the bar code label.

Solution
•
Aim the scanner beam to cross the entire bar code label in
one pass. Vary the scanning angle.
•
Check the quality of the bar code label. Scan 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 is enabled and
configured correctly. Use Intermec Settings to check the
symbologies. Expand Data Collection > Symbologies
beneath devices listed (scanner, virtual wedge) to check and
enable symbologies, then scan the bar code label again.
•
Make sure the computer application is expecting input from
a bar code. You may need to type this information instead
•
Check to see if the right scanner model is selected. To check
the setting go to Start > Settings > Control Panel >
Intermec Settings > Data Collection > Scanner Settings.
•
Check to see if the scanner cable is damaged.
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.
Confirm that no other application is currently using the COM
port or select another COM port for the scanner. If that does
not work, try to restart the computer to see if the COM port
becomes available.
•
Check to see if the Scanner Port Settings in Intermec
Settings match those settings programmed in the scan
engine.
•
The scanner may be in an unknown state. Reset the scanner
to the factory default settings by scanning the
manufacturer's configuration bar code, and reconnect the
scanner.
The scanner 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.
