Chapter 5 — Troubleshooting and Maintaining the CK31
Problems While Scanning Bar Codes (continued)
Problem
The scanner will not read the bar code
label.

Booting the CK31

You seldom need to warm or cold boot the CK31. The CK31
uses the configuration currently saved in flash memory during
the boot process.
You need to boot the CK31 when an application is locked up
and will not respond, when you upgrade the firmware, or when
you reflash the computer. The next instructions explain how you
warm and cold boot the CK31.

Solution
• 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.
• If you are using the 2D imager, set Lighting Mode to
Illum LED priority and set Lighting Goal to 100 (or
greater). Use Intermec Settings to change the
Lighting Mode setting.
• If the bar code is rotated, make sure that you have
1D Omni-directional scanning enabled. Use
Intermec Settings to enable 1D Omni-directional
scanning.
