You scan a valid bar code label to

Solution
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.
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.
The scanner window may be dirty. Clean the window
with a solution of ammonia and water. Wipe dry. Do not
obscured. allow abrasive material to touch the window.
Try these possible solutions in order:
The computer 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.
To operate the computer quickly and efficiently, you
should enable only the bar code symbologies that you are
going to scan.
