Zone processing Patch Detect  indicates whether or not the scanner detected a toggle patch on the document (side independent). If a toggle patch appears on a document, all images created from this document will have this indicator set in the image header. Toggle Patch  indicates the side of the document where the toggle patch was detected. If a toggle patch appears on a document, only the images created from the side of the document containing the patch will have this indicator set in the image header. Some applications have a requirement to store part of an image in color or grayscale and the rest of the image in black and white format (this saves storage space by not storing the entire image in color or grayscale). Zone processing is a fixed crop window (the zone) located relative to the upper left corner of a document. It allows the operator to select via the host application an area on the document to be delivered in color, grayscale or black and white format (a separate window for both black and white and color/grayscale may be defined). Different zones may be selected for both the front and rear of the image. This feature may be used in conjunction with auto cropping. Following is an example of producing a color zone.

Patch Detect
indicates whether or not the scanner detected a toggle
patch on the document (side independent). If a toggle patch appears on
a document, all images created from this document will have this
indicator set in the image header.
Toggle Patch
indicates the side of the document where the toggle
patch was detected. If a toggle patch appears on a document, only the
images created from the side of the document containing the patch will
have this indicator set in the image header.
Zone processing
Some applications have a requirement to store part of an image in color
or grayscale and the rest of the image in black and white format (this
saves storage space by not storing the entire image in color or
grayscale). Zone processing is a fixed crop window (the zone) located
relative to the upper left corner of a document. It allows the operator to
select via the host application an area on the document to be delivered
in color, grayscale or black and white format (a separate window for
both black and white and color/grayscale may be defined). Different
zones may be selected for both the front and rear of the image.
This feature may be used in conjunction with auto cropping. Following
is an example of producing a color zone.
