Scanning 2-3
Introduction
This chapter covers the techniques involved in scanning bar codes, beeper and LED definitions, and general instructions and tips about
scanning. Refer to Chapter 1, Getting Started for information on scanner components, and connecting host cables and the power
supply.
Active Scan Area
The active scan area is the area in front of the scanner window in which a bar code can be decoded. The dotted area in Figure 2-1
represents the active scan area for the scanner.

Scanning Bar Codes
Install and program the scanner. (Refer to each host chapter and Chapter 4, User Preferences, Chapter 13, Symbologies, Chapter 14,
Miscellaneous Scanner Options, and Advanced Data Formatting for instructions on programming the scanner.) For assistance, contact
the local supplier or call the Global Customer Interaction Center. See page xvi for contact information.
For the best scanning performance, the counter top or surface area covered by the active scan area should be a light, solid color. Avoid
designs (e.g., stripes or patterns). A rastering, 120-line, omni-directional scan pattern provides rapid, orientation-free scanning.
To scan a bar code:
1. Ensure all cable connections are secure.
2. Orient the item with the bar code facing the scanner window.
3. Move the item through the active scan area in the direction of the arrows (swipe scanning, see Figure 2-2), or place the item
in front of the scanner (presentation scanning, see Figure 2-3). Ensure that the scan lines cross every bar and space of the
symbol.
