With the standard range scan module, you will have the best success if you hold the
5020 so that the horizontal reading angle is near zero and the vertical reading angle is
near 20 degrees. To get the best scan angle, hold the 5020 so that the scan module is
pointing toward the bar code label. Tilt the 5020 up or down slightly (20 degrees). You
can also watch the laser beam. The laser beam becomes the brightest at the best scan
angle.
Optimum scan angles vary with the type and print quality of the bar code label, the
distance of the scanner from the label, and the lighting in the area.
Note: You should not scan the bar code label “straight on.” In a 2-degree conical
“dead zone” directly above the label, the laser beam may reflect back into the scanner
window and prevent the 5020 from reading the label. At certain angles and straight on,
you may not see the laser beam.
Scanning Options
You can set several configuration command parameters to configure the laser scanner to
meet your needs. There are several ways to set the scanner commands on the 5020. For
help, see Chapter 3, “Configuring the 5020.” For help using the scanner configuration
commands, see Chapter 8, “Configuration Command Reference.”
The parameters available are:
Decode Security
Defines the security level to use when decoding bar codes. When
you select a lower decode security level, the 5020 can decode bar codes with poorer
print quality.
Mode
Defines how the scanner operates when you press the Scan button or activate a
tethered laser scanner. In One-Shot mode, the laser turns on and stays on until you
release the button or scanner trigger, or a label is decoded. In Automatic mode, you can
continuously scan bar code labels without having to release the button or scanner trigger
between labels.
Redundancy
Defines the number of scans (voting) the scanner takes of the same label.
When set, voting requires the 5020 to decode the same bar code label multiple times
during a single scanner event, and compare the decoded information for a match before
signaling a good read.
Selection
Identifies the type of tethered scanner you have connected. The 5020 can
optimize the scanning performance by using the scanner you define in this command. If
you have a long-range scan module, Scanner Selection allows you to configure the
spotting beam.
Timeout Mode
Defines the maximum length of time the scanner stays on each time
you press the Scan button or activate a tethered laser scanner.
