Using the FR68 Series



Linear Scanning

FR68 Series with an integrated linear scanner have the following features:

z Reading of a variety of bar code symbologies, including the most popular linear, postal, and

1-D code types.

z 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:

z 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.

z 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.

z Hold the FR68 Series farther away for larger symbols.

z Move the FR68 Series closer for symbols with bars that are close together.



NOTE Scanning procedures depend on the application and FR68 Series configuration. An

application may use different scanning procedures from the one listed above.

1. Ensure that a scan enabled application is loaded on the FR68 Series.

2. Aim the scan exit window at the bar code.
