The compression rate can be changed in five levels from 1 to 5. (By default, the
compression rate is set to 3.)
Moving the slider bar to right increases the compression rate. Higher the
compression rate, the smaller the file size, but the image quality is degraded.
This setting takes effect on color images only. When images are saved as
monochrome images, this setting is ignored.

blurred. This setting is not suitable for scanning photographs and figures because
the image quality of highly-compressed photographs and figures is degraded.
