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
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 scan engine 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" for further information.
Does the scan engine read the barcode incorrectly?
If the scan engine reads a barcode, but the data is not displayed correctly on
the host screen:
• The scan engine may not be programmed for the appropriate terminal
interface.
For example, you scan “12345” and the host displays “@es%.”
Reprogram the scan engine with the correct Plug and Play or Terminal
selection barcode.
The scan engine may not be programmed to output your barcode data
properly.
