Problems Scanning Bar Code Labels (continued)
Problem Possible Solution
You cannot see a red beam of light from the
integrated scan module when you press the
Scan button and aim the scanner at a bar
code label. You may be too far away from the bar code label. Try moving closer
to the bar code label and scan it again. You need to be within the
scanning range to scan bar code labels. For help on scanning
distances, see “Physical and Environmental Specifications” in
Appendix A.
You may be scanning the bar code label “straight on.” Try changing
the scanning angle.
Do not look directly into the window area or at a reflection of
the laser beam while the laser is scanning. Long-term exposure to
the laser beam can damage your vision.
Attention Danger: Ne regardez pas directement la réflexion d’un
rayon laser ou dans la fenêtre du laser lorsque celui-ci est en
opération. Si vous regardez trop longtemps un rayon laser, cela
peut endommager votre vue.
An input device is not attached to the input
device module. Make sure an input device, such as a 1550 laser scanner, is attached
correctly to the input device module. You must install an input
device before scanning bar code labels.
The input device connected to the module
for cabled scanners does not appear to work
well or read bar code labels very quickly. Make sure the Scanner Selection command is set to the specific input
device you have attached. For help, see “Scanner Selection” in
Chapter 6 of the 2400 Family system manual.
Check the bar code symbologies you have enabled on the terminal.
Enable only the symbologies that you are using.
When you press the Scan button, the scanner
LEDs at the top of the keypad do not light
up. Move within 0.6 meters (2 feet) of a wall and press the Scan button
again. Make sure the scan module emits the red laser beam. If the
LEDs do not light, there may be a problem with them. For help,
contact your local Intermec service representative. If the laser beam
does not turn on, check the other problems in this section for a
possible solution.
When you release the Scan button, the
scanner LEDs at the top of the keypad do
not turn off. The scanner LEDs remain on if you configure the terminal to use
edge triggering. If you configure the terminal for level triggering and
the scanner LEDs remain on, there may be a problem with the
LEDs. Press the Scan button again without scanning a bar code label.
If the LEDs are still on, contact your local Intermec service
representative.
The integrated scan module does not read
the bar code labels quickly, or the scanning
beam seems to be faint or obscured. The scan module window may be dirty. Clean the window of the
scan module with a solution of mild soap and water. Wipe dry. Do
not allow abrasive material to touch the window.
You scan a valid bar code label to enter data
for your application. The data decoded by
the terminal does not match the data
encoded in the bar code label. The terminal 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 terminal quickly and efficiently, you should enable
only the bar code symbologies that you are going to scan. If you
enable multiple symbologies, the terminal may, on rare occasions,
decode a bar code according to the wrong symbology and produce
erroneous results.
