Single Code Centering
Scan Single Code Centering to target the bar code closest to the center of the
image. Singling out a bar code in this manner increases scanning accuracy when
there are multiple bar codes close together.
Custom Centering Settings
Use the following settings to customize your centering window. If a bar code is not
touched by a predefined window, it will not be decoded or output by the 8680i. If
centering is turned on by scanning Centering On, the 8680i only reads codes that
pass through the centering window you specify using the Top of Centering Win-
dow, Bottom of Centering Window, Left, and Right of Centering Window bar
codes.
In the example below, the white box is the centering window. The centering window
has been set to 20% left, 30% right, 8% top, and 25% bottom. Since Bar Code 1
passes through the centering window, it will be read. Bar Code 2 does not pass
through the centering window, so it will not be read.
Note: A bar code needs only to be touched by the centering window in order to be read. It
does not need to pass completely through the centering window.
