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 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 59 for further
information..
The scanner won’t read your bar code at all.
1. Scan the sample bar codes in the back of this manual. If the scanner reads the
sample bar codes, check that your bar code is readable.
Verify that your bar code symbology is enabled (see
Chapter 7 ).
b. If the scanner still can’t read the sample bar codes, scan All Symbologies
On , page 92.
If you aren’t sure what programming options have been set in the scanner, or if you
want the factory default settings restored, refer to
Activate Custom Defaults on
page 5.
