■ 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.
