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.

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.
