Chapter 6 — Troubleshooting and Maintaining the CK30
CK30 Handheld Computer User’s Manual 101
Problems While Scanning Bar Codes (continued)
Problem Solution
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
CK30 to use continuous/edge triggering. If you
configure the CK30 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.
You have an input device attached to the
CK30 and it cannot read any bar codes.
You may not be using an input device that is supported
with the CK30. Make sure you are using one of the
supported input devices and that you have selected the
correct scanner model using the Configuration Utility.
The input device attached to the
computer does not appear to work well
or read bar code labels very quickly.
Try setting the Scanner Model command to the specific
input device you have attached. Check the bar code
symbologies you have enabled on the CK30. Enable
only the symbologies that you are using.
The scanner will not read the bar code
label.
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 the Configuration Utility to check the
symbologies. On the Symbologies Menu, each
symbology that is enabled has a check mark (9) next to
the name of the symbology. 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 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.
