Using the MC65 2 - 23

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 — mini mum and maximum distances from
the bar code. This range varies according to bar code density and scanning dev ice optics.
Scanning within range brings quick and constant decodes; scanning too close or to o far away prevents
decodes. Move the scanner closer and further away to find the right working r ange for the bar codes being
scanned.
•
Angle
Scanning angle is important for promoting quick decodes. When laser beams re flect directly back into the
scanner from the bar code, this specular reflection can “blind” the scanner.
To avoid this, scan the bar code so that the beam does not bounce directly back. But don’t sc an at too sharp
an angle; the scanner needs to collect scattered reflections from the sca n to make a successful decode.
Practice quickly shows what tolerances to work within.
•
Hold the MC65 farther away for larger symbols.
•
Move the MC65 closer for symbols with bars that are close together.
Imager Scanning
To read a bar code, a scan-enabled application is required. The MC65 contains the DataWedge application that
allows the user to enable the camera, decode the bar code data and display the ba r code content.
1. Enable DataWedge.
a. Tap Start > Settings > System > DataWedge.
b. Tap Basic configuration > 1. Barcode input > 1. Block Buster Imager.
c. Tap 1. Enabled.
d. Tap 0. Back.
e. Tap 0. Back and then tap OK.
f. Tap Running to start the DataWedge process. The DataWedge Status changes to Ready.
g. Tap OK.
2. Launch an application that supports text inputs, such as Word Mobile 2010 or Excel Mobile 2010.
3. Point the exit window on the top of the MC65 at a bar code.
NOTE Scanning procedures depend on the application and MC65 configuration. An application may use different
scanning procedures from the one listed above.
