Problems While Scanning Bar Codes (continued)
Problem
When you release the 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
CK31G to use continuous/edge triggering. If you
configure the CK31G for level triggering and the Good
Read light remains on, there may be a problem. Press
the Scan button or pull the trigger again without
scanning a bar code label. If the light is still on, contact
your local Intermec service representative.
Make sure you aim the scanner beam so it crosses the
entire bar code label in one pass.
The angle you are scanning the bar code label may not
be working well, or you may be scanning the label
"straight on." Try scanning the bar code label again, but
vary the scanning angle.
The bar code label print quality may be poor or
unreadable. To check the quality of the bar code label,
try scanning 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 you are scanning is
enabled. Use Intermec Settings to check the
symbologies. If your bar code symbology is disabled,
enable it and then try scanning the bar code label again.
Make sure that the application you are running on the
computer is expecting input from a bar code. You may
need to type this information instead of scanning it.
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.
To operate the computer quickly and efficiently, you
should enable only the bar code symbologies that you
are going to scan.
