■ Brightness (Black and White scanning only)
Sets the density for scanning black-and-white images.
Moving the slider to the left will lighten the scanned image, while moving the slider to
the right results in a darker scanned image.
* This is only available when the "Color mode:" is set as "B&W", or when "Auto
Color Detection" is selected and the document is recognized as back and white.
■ Setting for text only document.
Select the checkbox as follows according to the type of your document.
• Select this checkbox when scanning documents containing only printed or hand-
written text.
• Clear this checkbox when scanning documents containing photographs.
* This is only available when the "Color mode:" is set as "Color", or when "Auto
Color Detection" is selected and the document is recognized as color.
■ Allow automatic blank page removal.
This setting automatically detects blank pages in the document stack and automatically
removes them from the output.
For example, when a stack of documents containing both two-sided and one-sided
documents is scanned in Duplex mode, this feature removes only the backsides (i.e.
blank pages) of one-sided documents from the output images.
* No scanned images are generated if all the sheets in the document stack are
recognized as blank pages.
■ Allow automatic image deskew.
This setting automatically detects skewed documents and corrects them for the output
data. Up to +-5 degrees of skews can be corrected.
ATTENTION
The following types of documents may be accidentally recognized as
blank pages:
• Almost blank documents containing only a few characters
• Documents of only one color (including black) and without any patterns,
lines, or characters
ATTENTION
This function judges a document’s skew based on the characters on the
document. So the detection may not work properly for the following kinds
of documents:
• Documents on which the pitches of lines or characters are extremely
narrow, or characters are overlapped
• Documents which have many outline characters or similar font styles
• Documents with only a few characters
• Documents with many photographs or figures
• Documents with a background pattern behind the characters
• Documents with characters printed in various direction (e.g. plans, etc.)
• Documents with long diagonal lines
• Documents with handwritten characters
*When you scan such documents, clear the checkbox.
