The Toggle patch is a type 4 patch that is used to trigger the scanner to
switch from the current image stream (black and white) to the
alternative image stream (color/grayscale).
1. Prepare documents with a patch Type 4 before and after any color/
grayscale documents.
2. Configure image processing parameters for all four images. Before
enabling the scanner, select only the front and back black and white
images to be retrieved.
3. Configure the scanner to alternate both sides when a toggle patch is
detected.
4. Start scanning.
Images will begin in black and white and will change to color/grayscale
when the first toggle patch is detected. Images will remain color/
grayscale until the next toggle patch is detected. Images of the toggle
patch sheet will not be returned to the host unless you also enable
patch reading and select the Type 4 patch.
1. Configure image processing parameters for all four images. Before
initiating the scanner, select only the front and back black-and-white
images to be retrieved.
2. Enable Auto Color Detection by choosing Low, Medium, High or
Custom.
3. Start scanning.
The scanner will determine if it should return a black-and-white or color/
grayscale image based on a document-by-document analysis of the
color content.
