Troubleshoot a Corded Scanner
The scanner automatically performs self-tests whenever you turn it on. If your
scanner is not functioning properly, review the following Troubleshooting Guide
to try to isolate the problem.
Is the power on? Is the aimer on?
If the aimer isn’t illuminated, check that:
•
The cable is connected properly.
•
The host system power is on (if external power isn’t used).
•
The trigger works.
Is the scanner having trouble reading your symbols?
If the scanner isn’t reading symbols well, check that the symbols:
•
Aren’t smeared, rough, scratched, or exhibiting voids.
•
Aren’t coated with frost or water droplets on the surface.
•
Are enabled in the scanner or in the decoder to which the scanner connects.
Is the barcode displayed but not entered?
The barcode is displayed on the host device correctly, but you still have to press a
key to enter it (the Enter/Return key or the Tab key, for example).
•
You need to program a suffix. Programming a suffix enables the scanner to
output the barcode data plus the key you need (such as “CR”) to enter the
data into your application. Refer to
further information.
If you aren’t sure what programming options have been set in the scanner, or if
you want the factory default settings restored, refer to
