Adjusting Scanned Image
• I want to enhance text on a document with a dark background
Set “Mode” to [Text Enhancement]. The background of the document is
removed to enhance the text.
See “ISIS Driver Settings b,” on p. 50, and “TWAIN Driver Settings b,”
on p. 52.
• I want to enhance text on a document that has light text on a
light background
Set the scanning mode to [Advanced Text Enhancement II]. The background
is eliminated or processed out of the document and the text is enhanced.
See “ISIS Driver Settings b,” on p. 50, and “TWAIN Driver Settings b,”

• I want to lessen the moire effect that occurs when color
documents, such as magazine photos, are scanned
Scan at a resolution of 400 dpi or less and at [256 shade grayscale] or [24 bit
smoothing colors]. This averages the image to suppress moire.
