Troubleshooting
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 red illumination beam on?
If the red illumination beam isn't illuminated, check that:
1. The cable is connected properly.
2. The host system power is on (if external power isn't used).
3. The trigger works.
Is the scanner having trouble reading your symbols?
If the scanner isn't reading symbols well, check that the symbols:
1. Aren't smeared, rough, scratched, or exhibiting voids.
2. Aren't coated with frost or water droplets on the surface.
3. Are enabled in the scanner or in the decoder to which the scanner connects.
Is the bar code displayed but not entered?
The bar code 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 bar code data plus the key you need (such as "CR") to enter the data
into your application. Refer to
"Prefix/Suffix Overview" on page 3-1
for further
information.
