Use ScanDiagnostic to Troubleshoot the Scanner
Use the ScanDiagnostic application to troubleshoot problems such as
the inability to read a bar code or a scanner that does not turn on.
1 From the Home menu, tap Start > ScanDiagnostic.
2 From the Scan Health screen, select the scanner you want to
troubleshoot and then tap Diagnose.
The application checks to make sure the scanner is enabled and
checks settings to make sure they are optimized.
3 From the Scan Test screen, press and hold the Press to Scan
button while aiming at the bar code you want to read.
After the computer scans the bar code, it beeps and the label data,
data length, and symbology appear on the screen.
4 Press the right arrow button to view any recommended settings.
5 To accept the recommended settings, tap Apply.
6 Tap OK to exit.
The scanner does not read the bar
code labels quickly, or the
scanning beam seems to be faint or
obscured.
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.
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.
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.
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. Check enabled bar code symbologies and enable
only the symbologies being used.
