Section Area (Multi-area Settings)

This function permits the specification of up to four rectangular areas of any size within the scanning area, each of which can be set as the scanning area. When overlapping areas are set, the area that was set last takes priority.

For example, when a single original contains both text and photos, specify rectangular areas for each, and then set binary scanning mode for the text areas and halftone scanning mode for the photographs. This function allows each area to be scanned in its respective scanning mode in one scan.

Limitation

❒During double-sided scanning, this function is valid only for the front side of the original.

Note

❒Note that scanning might not be performed in the specified manner if any of the four rectangular areas overlap. In this case, either decrease the number of rectangles, or else reduce them in size.

❒This function is valid only when the optional Image Processing Unit Type A is installed.
