Presentation Centering
Use Presentation Centering to narrow the scanner’s field of view when it is in the stand to make sure the scanner reads
only those bar codes intended by the user. For instance, if multiple codes are placed closely together, Presentation Center-
ing will insure that only the desired codes are read.
Note: To adjust centering when the scanner is hand-held, see
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.
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.

centering window. Then scan the percent you want to shift the centering window using digits on the inside back cover of
