Problem
When you release a Scan button
or handle trigger, the Good Read
light does not turn off.
The scanner will not read the bar
code label.
The scanner does not read the bar
code labels quickly, or the
scanning beam seems to be faint
or obscured.
You scan a valid bar code label to
enter data for your application.
The data decoded by the scan
module does not match the data
encoded in the bar code label.
Solution
The Good Read light will remain on if
you configure the computer to use
continuous/edge triggering. If you
configure the computer for level
triggering and the Good Read light
remains on, there may be a problem. Press
one of the Scan buttons or pull the
trigger again without scanning a bar code
label. If the light is still on, contact your
local Intermec representative.
•
Aim the scanner beam to cross entire
bar code label in one pass. Vary the
scanning angle.
•
Check the quality of the bar code label,
Scan a bar code label that you know
will scan. Compare the two bar code
labels to see if the bar code quality is
too low. You may need to replace the
label that you cannot scan.
•
Make sure the bar code symbology is
enabled and configured correctly. Use
Intermec Settings to check the
symbologies. Expand
Collection > Symbologies
devices listed (scanner, virtual wedge)
to check and enable symbologies, then
scan the bar code label again.
•
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 ammonia
and water. Wipe dry. Do not allow
abrasive material to touch the window.
The computer may have decoded the bar
code label in a symbology other than the
label's actual symbology. Try scanning
the bar code label again. Make sure you
scan the entire label.
