are more likely to be skipped.

Document orientation
Rotates the scanned image a specified amount.
Hint
If you select [Auto], the orientation of text within the document is
detected and the image is rotated so that the orientation of the
text is correct.
IMPORTANT
The scanning speed may be reduced when [Auto] is selected.
Deskew
The scanner detects from the scanned image that the
document was fed askew and then straightens the image.
• Prefer Quality
Image processing is performed to minimize the loss of
quality of an image that has deteriorated as result of
deskewing.
• Prefer Speed
The image deteriorates slightly as a result of deskewing.
IMPORTANT
If you select [Prefer Quality], the scanning speed is reduced. If
you are scanning a large number of pages, select [Prefer
Speed] to prevent a decrease in scanning speed.
Bleed-through reduction
Eliminates bleed-through images, in which images on the
reverse side of a scanned document appear on the scanned
page, such as when scanning thin documents with text or
images on both sides.
IMPORTANT
Bleed-through reduction cannot be set when the [Text enhance]
mode is selected.
