Problems While Scanning Bar Codes
Problem Solution
You cannot see a red beam
of light from the connected
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 ft) of a wall and test the
scanner. You need to be within the scanning range to scan bar
code labels.
The input device attached
to the computer does not
appear to work well or read
bar code labels very
quickly. There are two possible problems:
• Try setting the Scanner Model command to the specific input
device you have attached.
• Check the bar code symbologies you have enabled on the CV30.
Enable only the symbologies being used.
You scan a configuration
command such as Beeper
Volume, and you hear three
low beeps. If you are using Intermec Setting, you cannot scan configuration
commands. Exit Intermec Settings to scan configuration
commands.
You scan or enter an option
for the Scanner Model
configuration command
and you hear three low
beeps. You may have scanned or enter a Scanner Model command that
does not apply to the type of scanner that you have installed. Try
scanning or entering the Scanner Model command again and select
an option for the type of device you are using.
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. 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.
The scanner does not read
the bar code labels quickly,
or 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.
