If a bar code is not touched by a predefined window, it will not be decoded or output by the scanner. If Presentation Center-
ing is turned on by scanning Presentation Centering On, the scanner only reads codes that pass through the centering
window you specify using the Top of Presentation Centering Window, Bottom of Presentation Centering Window,
Left, and Right of Presentation 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.
100
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 Presentation 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 using digits on the inside back cover of
this manual. Scan Save. Default Presentation Centering = 40% for Top and Left, 60% for Bottom and Right.
