Scan (Macintosh)
Image Selection check boxes
Select the check boxes to customize the scan type. We added this sentence to clarify the difference between
Image Selection check boxes and Image Selection group. For example, to scan both the front and back of
a color document page in color, select the Front Color and Back Color check boxes. For a black and white
scan of the front and a color scan of the back, select Front B&W and Back Color.
NOTE
• Select more than one image type check box to generate multiple scan results from a single scan. For
example, if you select Front Color and Front Gray, and then scan your document, scan data in both color
and gray is saved.
• If you select Front Auto Detection, you must select Back Auto Detection as a back image type, and vice
versa. These two options work only with each other.
Image Selection group
The Image Selection group lets you configure detailed settings used when scanning in each color mode.
Select an image type and customize detail settings. You can apply different settings to each image type.
Image Type Description
Color Select Color if your original is in color and you want an exact copy.
Gray Select Gray if your original contains shades of gray.
B&W Select B&W if your original is typed, written in pencil, or written in pen.
Auto Detection Select Auto Detection to automatically detect and scan the front or back of your color document.
If your document is in color, the scanner will automatically scan the document as a color image.
If your document is not in color, choose either Black and White or Gray from the Non-Color
Selection pop-up list. Use this option if your document is multi-page and includes both color and
black and white.
Binarization / Document Type
This field name changes based on your choice in the Image Selection group.
 Binarization (B&W mode only)
Binarization is the process of converting a grayscale or color image to a black and white image. There are
several methods of performing this conversion.
Conversion Methods
Dynamic Threshold
Fixed Processing
Halftone 1-5
Description
Select Dynamic Threshold to allow the scanner to dynamically evaluate each document
to produce the highest quality image. Select this option to scan documents containing
faint text, shaded background, or color background. If you select Dynamic Threshold:
Threshold, Brightness, and Contrast are not available.
Select Fixed Processing for black and white and other high-contrast documents. A single
level is set to determine the black and white transition. The threshold is programmable
over the entire density range. If you select Fixed Processing, Contrast is not available.
Select Halftone to view a gray image composed of different-sized dots. In other
machines, this is sometimes called "Grayscale".
