How to Scan
Quick Reference Guide 1-9
Troubleshooting
The scanner will automatically perform a set of self-tests whenever you
turn it on. If your scanner doesn’t seem to be functioning properly, fol-
low these steps to try and isolate the problem.
1. Is the power on? Does the illumination beam come on?
If no illumination beam, check that...
• all connections are fully seated and in the appropriate port(s).
• the host system power is on (if external power isn’t used).
• the trigger works.
2. 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. See the Product Reference Guide
(PRG) for more about configuring the scanner to read symbolo-
gies).
3. 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 or Tab key, for
example).
You need to program a suffix which enables the scanner to output
the bar code data plus the key you need (such as a carriage return
“CR”) to enter the data into your application. Refer to the PRG
for further information.
4. Does the scanner read the bar code incorrectly?
If the scanner reads a bar code, but the data is not displayed cor-
rectly on the host screen:
• The scanner may not be programmed for the appropriate termi-
nal interface. For example, you scan “12345” and the host dis-
plays “@es%.” Reprogram the scanner with the correct interface
selection bar code. See
Programming
in this manual and/or the
PRG.
