9-2 Troubleshooting
The scan engine automatically performs self-tests whenever you turn it on.
If your scan engine is not functioning properly, review the following
Troubleshooting Guide to try to isolate the problem.
Is the power on? Is the red or green aiming illumination line on?
If the aiming line doesn’t appear, check that:
• The cable is connected properly.
• The host system power is on (if external power isn’t used).
Is the scan engine having trouble reading your symbols?
If the scan engine 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 scan engine or in the decoder to which the scan engine
