Problems Reading Bar Codes
Problem
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.
When you release the Scan
button or scan handle trigger, the
Good Read LED does not turn
off.
The scanner cannot read the bar
code.
The scanner cannot read the bar
code quickly, or the scanning
beam seems to be faint or
obscured.
Chapter 8 — Troubleshoot and Maintain the Computer
Possible Solution
•
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.
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.
•
Position the scanner beam so that it
crosses the entire bar code label in one
pass. Try to vary the scanning angle.
•
Check the quality of the bar code label.
Scan a bar code label that you know
scans properly. Compare the quality of
the two bar code labels. You may need
to replace the label that you cannot
scan.
•
Make sure the bar code symbology is
enabled and configured correctly.
Start the Settings app and check the
scanner settings to verify that
decoding is enabled for the symbology
you are using.
•
Make sure the computer application is
expecting input from a bar code. You
may need to type this information
instead.
The scanner window may be dirty. Clean
the window with a solution of mild soap
and water. Wipe dry. Do not allow
abrasive material to touch the window.
