Resetting The Cn3 - Intermec CN3 Series User Manual

Problems While Scanning Bar Codes (continued)
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. Use
Intermec Settings to check the symbologies. Expand
Data Collection > Symbologies beneath 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.
You rarely need to reset the computer. If the computer does not
resume after pressing the Power button, or if the computer or an
application lock up, you may need to reset the CN3. The CN3
uses the configuration currently saved in flash memory during
the boot process. There are three ways to reset the CN3:
• Warm booting the CN3
