[Auto Color Detection]
The document is detected as black-and-white or color
before the scanned image is saved.
Selecting this mode enables the [Setting] button for
opening the [Auto Image Type Detection Settings] dialog
box, where you can make settings for auto image type
detection. (See “[Auto Image Type Detection Settings]
Dialog Box” on p. 8-10.)
IMPORTANT
Depending on the application program, operation may become
unstable when [Auto Color Detection] is enabled. In that case,
[Auto Color Detection] should be disabled.

IMPORTANT
• Select [Auto-detection] to scan the following kinds of
documents.

is set to 300 dpi or lower, and the [Image Quality] setting is
enabled when the resolution is set to 400 or 600 dpi.
