Bar Code Labels Will Not Scan
Problem or Message Solution
You cannot see a red beam of light from the
integrated scan module when you aim the
scanner at a bar code label and press the Scan
button or pull the trigger on the handle. 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 scanning it again.
•
You may be scanning the bar code label “straight on.” Try changing
the scanning angle until the laser beam is the brightest. This is the
best scanning angle.
You can test the effective range of the scanner. Move within 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 “Physical and
Environmental Specifications” in Appendix A.
Warning
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.
Avertissement
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.
You cannot scan a bar code label because an
input device is not attached to the tethered
scanner port. Make sure an input device, such as a 1550 laser scanner, is attached
correctly to the tethered scanner port. You must install an input device
before scanning bar code labels.
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 scan module window
with a solution of ammonia and water. Wipe dry. Do not allow abrasive
material to touch the window.
You have an input device attached to the
tethered scanner port and cannot read any bar
code labels. You may not be using an input device that is supported with tethered
scanner port. Make sure you are using one of the supported input
devices:
•
Intermec 126X, 127X, and 128X wands
•
Intermec 151X, 1545, and 1550 laser scanners
Also make sure that the 5020 is configured for the scanner you are
using. In the Configuration application under Data Collection, select
Scanner and then Selection. For more information, see “Using the
Configuration Application on the 5020” in Chapter 3.
