Centering
barcodes intended by the user. For example, if multiple codes are placed closely together,
centering will insure that only the desired codes are read. If a
barcode is not touched by a
on by scanning Centering On, the scanner only reads codes that pass through the center -
ing window you specify using the Top of Centering Window, Bottom of Centering Window,
Left, and Right of Centering Window barcodes.
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 center - ing
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 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
barcodes at the end of this chapter. Lastly scan Save.
Default Centering is 40% for Top and Left, 60% for Bottom and Right.
