Solution
Make sure you are using a supported scanner, as
listed in "Attaching a Scanner to the Serial Port"
on page 30. If you are using a supported scanner,
try these solutions in order:
You may be too far from the bar code label.
•
Move closer to the bar code label and try 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 try
again. You must be within the scanning range
to scan bar code labels. For help, see "Scanning
Bar Codes" on page 22.
If your CK31 contains an imager:
If the CK31 is configured for continuous/edge
•
triggering, the red beam should remain on. This
is not a troubleshooting issue.
If the CK31 is configured for level triggering
•
(default), the red beam should turn off. If the
red beam remains on, there may be a problem
with the scanner. Press the Scan button or pull
the trigger again without scanning a bar code
label. If the red beam is still on, contact your
local Intermec service representative.
If your CK31 contains a laser scanner:
If you set the Aim then Scan parameter to
•
Enable and the Turn off after good read
parameter to Disable/Auto-Trigger, the red
beam should remain on. This is not a
troubleshooting issue.
If those parameters are not configured, the red
•
beam should turn off. If the red beam remains
on, there may be a problem with the scanner.
Press the Scan button or pull the trigger again
without scanning a bar code label. If the red
beam is still on, contact your local Intermec
service representative.
