Troubleshooting 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 button 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 Prefix/Suffix Overview on page 61 for further
information.
The scanner won’t read your barcode at all.
