When [Auto], [RGB Color], or [Grayscale] is selected as described in "6.9.2 Color Mode" (page 363), it is also possible to set the compression rate of scanned data.

For photos and images, a high compression rate can be used to create a smaller file. Changing the compression rate affects the scanned data in the following ways.
