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 Barcode 1
passes through the centering window, it will be read. Barcode 2 does not pass
through the centering window, so it will not be read.
Note: A barcode 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 Presentation Centering On, then scan one of the following barcodes to
change the top, bottom, left, or right of the centering window. Then scan the
percent you want to shift the centering window using digits from the Programming
Chart, beginning on page 222, and then scan Save. Default Presentation Centering
= 40% for Top and Left, 60% for Bottom and Right.
