Scanning With the Laser Scanner or Linear Imager

16
Description
Indicates a good scan.
Indicates the scanner is initializing.
Indicates the keypad is shifted to Alpha (green) and the computer is turned on.
When the keypad is in alpha mode, the LED temporarily switches from red to yellow to
indicate a good scan. The yellow LED also indicates a Calendar or Task activity.
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.
Use the internal scanner to scan and enter bar code data. The type of
scanner you are using and the type of bar code you are decoding determines
the way you scan the bar code. The computer supports the scanning of 1D
linear bar codes and 2D images, depending on the scanner model you chose
to purchase. Plus, if you are using an integrated handle or a scanner
attached to the serial port, the way you scan bar codes is different.
When you unpack the computer, these bar code symbologies are enabled:
• Code 39
• Code 128
• PDF417 (if supported)
• UPC/EAN
• DataMatrix (area imagers only)
If you are using bar code labels that are encoded in a different symbology,
you need to enable the symbology on the computer. Use Intermec Settings
to enable and disable symbologies for your scanner. For help using Intermec
Settings, see "Configuring the Computer With Intermec Settings" on
page 38.
For information on scanner reading distances, see
Distances" on page 90. The following two sections describe how to scan a
bar code label with the laser scanner (EL10), linear imager (EV10), and area
imager (EA11).
If your computer has a standard range laser or a linear imager, use the
following procedure to practice scanning a bar code. The linear imager can
decode PDF417 bar codes as well as bar codes with high-density, low-
density, and poor quality in any lighting conditions. For help scanning
PDF417 bar codes, see the procedure on the next page.
