6.9.9 Compression
When [Auto], [RGB Color], or [Grayscale] is selected for the "6.9.2 Color Mode" (page 364), it is
also possible to set the compression level.
Setting a compression level (1 to 5) reduces the file size when scanning documents such as photo-
graphs or figures.
Changing the compression level affects the scanned data in the following ways.
1. On the "Scan Settings" screen, select the [Save] tab.
2. Press the [Compression] button.
The "Compression" screen appears.
3. Select a compression level.
The lower the selected compression level is, the higher the quality of the resulting scan will
be, but at the expense of a larger file.
When PDF format is selected in "6.9.6 File Format" (page 371), "High Compression for
Color PDF" can be used.
Selecting a compression level returns you to the "Scan Settings" screen. The selected
level is displayed to the right of the [Compression] button.
