Kodak i800 Series manual January

Single-stream duplex alternating between bi-tonal and color/grayscale using the scanner Toggle patch

This job stream is available for i820 and I840 Series Scanners.

The Toggle patch is a type 4 patch that is used to trigger the scanner to switch from the current image stream (bi-tonal) to the alternative image stream (color/grayscale).

The example illustrates using patch type 4 in the same way which the “color patch” is utilized on the Kodak Digital Science Scanner 3590C where it starts using bi-tonal.

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 initiating the scanner, select only the front and rear bi-tonal images to be retrieved.

3.Select both sides from the Toggle Patch drop-down box.

4.Start scanning.

Images will begin in bi-tonal 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.
