Problems Reading Bar Codes
You can troubleshoot problems that prevent you from reading bar
codes, such as the appropriate symbology not being enabled. Before
you call Intermec Product Support, look for your problem in the next
table, and try the possible solutions.
Problems Reading Bar Codes
Problem Possible Solution
You cannot see the illumination
beam or frame from the scanner
when you press the Scan button
and aim the scanner at a bar code
label.
• You may be too far away from the bar
code label. Try moving closer to the
bar code label and scan it again.
• You may be reading the bar code label
“straight on.” Change the reading
angle and try again.
When you release the Scan
button or scan handle trigger, the
Good Read LED does not turn
off.
If you configure the computer to use
continuous/edge triggering, the Good
Read LED stays on. If you configure the
computer for level triggering and the
Good Read LED stays on, there may be a
problem. Press the Scan button or pull
the trigger again without scanning a bar
code label. If the LED is still on, contact
Intermec.
