6.2 Troubleshooting
The SCANTEAM 3400 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.
Troubleshooting Guide
Is the power on? Is the red illuminated beam on?
If the red scan beam on the 3400 isn’t illuminated, check that:
➊ the cable is connected properly.
➋ the host system power is on (if external power isn’t used).
➌ the trigger works (if the 3400 is equipped with one).
If the 3400 turns on when trigger is pulled, the 3400 is in
Manual trigger mode. To change to Auto trigger mode go
to Section 3.9, Trigger Mode Selection.
Is the 3400 having trouble reading your bar codes?
If the 3400 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 3400 or the decoder the 3400 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 3400 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.
