Product Description
1.8.4 Reading Area
This function allows you to limit the scan to a specified portion of the document. Set the reading
area by specifying the reading lengths, in units of dots, for both the main scan and the sub scan.
The maximum selectable reading area is determined by the resolution and zoom settings. To
specify a smaller reading area, indicate the rectangular area and offset from the origin. The smaller
area must lie within the maximum selectable area. The following figure shows the image as
viewed from the scanner.

Color page sequence mode
The scanner scans the document three times to scan green, red, and blue separately. Page
sequence mode is faster than line sequence mode.
Color line sequence mode
The seamer scans the document once, scanning green, red, and blue simultaneously. This
scanning method allows you to use the color correction function.
Monochrome mode
The scans the document once, and scans the image in monochrome. In standard monochrome
scanning, all green, red, and blue lights are use to produce white light, and the undesirable
dropout color is minimized.
Dropout color (monochrome scanning only)
The dropout
color
is the color that is not recognized by the scanner and can be used to erase an
unwanted color. You can choose green, red, or blue.
