Chapter 10 Practical Examples

When you want to remove the black spots from scanned images when scanning documents with punch holes (when the background is set to black)

When the background color is set to black on the [Others] tab sheet, select [Punch Hole Removal] on the [Image processing] tab sheet. The black spots from punch holes in documents are removed from scanned images. (See

p. 8-16.)

Hint

When the background color is set to white, [Punch Hole Removal] is disabled. When the background color is set to white and a document with punch holes is scanned, the edges of holes may still appear in the images.

When you want to match the orientation of images to the text when scanning a mixture of pages with different text orientations

Select [Text Orientation Recognition] on the [Image processing] tab sheet. (See p. 8-16.)

The text orientation on each page is detected, and the scanned image is rotated in 90-degree increments to correct the orientation.

Hint

When [Text Orientation Recognition] is selected, image rotation is disabled.

When you want to rotate the images of a document loaded horizontally to correct the orientation

Specify the rotation angle with [Document Orientation] on the [Image processing] tab sheet. (See p. 8-16.)

Hint

Images are rotated as follows according to the orientation of the loaded document and the selected angle.
