Using the FR6874
43
Data Capture
The FR6874 offers one type of data capture option: linear scanning
NOTE
To perform data capture a scanning enabled application must be installed on the FR6874. A sample
scanning application can be downloaded from the Motorola Support site at http://support.symbol.com.
Linear Scanning
FR6874 with an integrated linear scanner have the following features:
•
Reading of a variety of bar code symbologies, including the most popular linear, postal, and 1-D code
types.
•
Intuitive aiming for easy point-and-shoot operation.
Scanning Considerations
Typically, scanning is a simple matter of aim, scan, and decode and a few quick trial efforts master it. However,
consider the following to optimize scanning performance:
•
Range
Any scanning device decodes well over a particular working range — minimum and maximum distances from
the bar code. This range varies according to bar code density and scanning device optics.
Scanning within range brings quick and constant decodes; scanning too close or too far away prevents
decodes. Move the scanner closer and further away to find the right working range for the bar codes being
scanned.
•
Angle
Scanning angle is important for promoting quick decodes. When laser beams reflect directly back into the
scanner from the bar code, this special reflection can “blind” the scanner.
To avoid this, scan the bar code so that the beam does not bounce directly back. But don’t scan at too sharp
an angle; the scanner needs to collect scattered reflections from the scan to make a successful decode.
Practice quickly shows what tolerances to work within.
•
Hold the FR6874 farther away for larger symbols.
•
Move the FR6874 closer for symbols with bars that are close together.
NOTE
Scanning procedures depend on the application and FR6874 configuration. An application may use different
scanning procedures from the one listed above.
1.
Ensure that a scan enabled application is loaded on the FR6874.
2.
Aim the scan window at the bar code.
