Problems While Scanning Bar Codes
Problem Solution
You cannot see a red beam of light from the scanner when
you press the Scan button and aim the scanner at a bar code
label.
You may be too far away from the bar code label. Try
moving closer to the bar code label and scan it again.
You may be scanning the bar code label “straight on.”
Change the scanning angle and try again.
Move within 2 feet of a wall to test the effective scan of the
scanner. For help scanning bar codes, see “Scanning Bar
Codes” on page 5.
When you release the Scan button or handle trigger, the
Good Read light does not turn off.
The Good Read light will remain on if you configure the
CK61 to use continuous/edge triggering. If you configure
the CK61 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
representative.
The input device attached to the CK61 does not work well
or read bar code labels very quickly.
Set the Scanner Model command to the specific attached
input device. Check enabled bar code symbologies and
enable only the symbologies being used.
The scanner will not read the bar code label. 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.
Ensure the bar code symbology is enabled. Use the Intermec
Settings applet 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.
Ensure the CK61 application is expecting input from a bar
code. You may need to type this information instead.
The scanner does not read the bar code labels quickly, or the
scanning beam seems to be faint or obscured.
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.
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.
CK61 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 receive a message reading “Scanner Communication
Failure” when trying to connect a 1551E or 1553 decoded
scanner.
Make sure that:
• You are using the correct cable.
• The scanner cable is attached correctly. When you attach
the scanner to the port, it should emit a single power up
beep.
• Try enabling the port state using the Intermec Settings
applet.
• Try upgrading the scanner firmware.
• Select ASCII as the scanner model.
Your 1551E or 1553 scanner was working fine, but after
changing the port setting you cannot change the
configuration.
1551E or 1553 scanner port must use the correct RS-232
settings to allow configuration in the Intermec Settings
applet. Disable, then enable the scanner port state.
Configuration settings in the Intermec Settings applet do
not match the settings on your 1551E or 1553 Scanner.
Disable, then enable the scanner port state to synchronize
the CK61 settings with the scanner.
