Scanned images are rotated as follows according to the orientation of loaded documents and the
selected angle.
• To rotate images to match document text
Select [Text Orientation Recognition] on the [Image processing] tab sheet. The text orientation on
each page is detected, and the scanned image is rotated in 90-degree increments as needed for
normalization.
When [Text Orientation Recognition] is selected, image rotation is disabled.
• To reverse black and white in scanned images (TWAIN driver only)
Select [Reverse Image] on the [Image processing] tab sheet. Black and white are reversed in
scanned images. (See “[Reverse Image] Check Box (TWAIN driver only),” on p. 7-18.)
• To ignore a particular color when scanning
Select a color to be ignored (dropped out) in [Color drop-out] on the [Image processing] tab
sheet, and that color will be eliminated from scanned images. (See “Color Drop-Out,” on p. 7-18.)
• To enhance a particular color when scanning
Select the color to be enhanced in [Color drop-out] on the [Image processing] tab sheet, and that
color will be enhanced in scanned images. (See “Color Drop-Out,” on p. 7-18.)
