Troubleshooting
The HandĆHeld Decoded Output scanner automatically performs selfĆtests
whenever you turn it on. If your scanner is not functioning properly, review the
following Troubleshooting Guide to try to isolate the problem.
Troubleshooting Guide
Is the power on? Is the red illuminated beam on?
If the red scan beam on the scanner isn't illuminated, check that:
➊ the cable is connected properly
.
➋ the host system power is on (if external power isn't used).
Is the scanner having trouble reading your bar codes?
If the scanner isn't reading bar codes well, check that the bar codes:
➊ aren't smeared, rough, scratched, or exhibiting voids.
➋ aren't coated with frost or water droplets on the surface.
➌ are enabled in the scanner or the decoder the scanner is connected to.
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 scanned bar
code plus the key you need (such as a CR," carriage return) to enter
the bar code into your application. (See Suffix Selection in Section 2,
Output Parameters Menu.)
