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.
Scan Centering On, then scan one of the following bar codes to change the top,
bottom, left, or right of the centering window. Then scan the percent you want to
shift the centering window from the
then scan Save. Default Centering = 40% for Top and Left, 60% for Bottom and
Right.
