The default centering window is a 128x96 pixel area (640x480 default image size) in the center of
the imager‟s field of view. The following diagram illustrates the default top, bottom, left, and right
pixel positions, measured from the top and the left side of the imager‟s field of view.
If a bar code is not within the predefined window, it will not be decoded or output by the imager. If
centering is turned on by scanning Centering On, the imager only reads codes that intersect the
centering window you specify using the Top, Bottom, Left, or Right bar codes.
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 using
digits on the inside back cover of this manual. Scan Save. Default Centering = 40% for Top and
Left, 60% for Bottom and Right.
