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.
There are two possible problems:
•
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.
You can test the effective range of the scanner. Move within
61 cm (2 feet) of a wall and test the scanner. You need to be
within the scanning range to scan bar code labels. For help on
scanning distances, see Appendix A, “Specifications.”
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 scans. 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. For help, see “Configuring Bar Code Symbologies”
on page 30. 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 CK1 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.
