Chapter 4 — Troubleshooting and Maintaining the Computer
Problems While Scanning Bar Codes (continued)
Problem
When you release
Scan button, the
Good Read LED
does not turn off.
The imager does not
read the bar code
label.
The imager does not
read the bar code
labels quickly, or the
scanning beam
seems to be faint or
obscured.
The scanned bar
code data that
appears in your
application does
not match the data
encoded in the bar
code label.
Possible Solution
If the mobile computer is configured to use
continuous/edge triggering, the Good Read LED
stays on.
If the mobile computer is configured to use level
triggering, there may be a problem. Press the Scan
button again without scanning a bar code label. If the
LED is still on, contact your local Intermec
representative.
•
Aim the scanning beam so that it crosses the entire
bar code label in one pass. Try changing the scan
angle.
•
Check the quality of the bar code label, Scan a bar
code label that you know scans well. 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. For
help, see the Data Collection Resource Kit which is
part of IDL. You can download the resource kit
from www.intermec.com/idl.
•
Make sure the application is accepting input by
scanning a bar code. You may need to type this
information instead.
The imager 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 mobile computer may have decoded the bar code
label in a different bar code symbology. Try scanning
the bar code label again. Make sure you scan the
entire label.
