When the scanner detects that a skewed page is contacting the edge
of the transport path, an error message is displayed and transport
stops.
IMPORTANT
• A page that becomes skewed while it is fed is only detected by the
sensors as skewed if it contacts the edge of the transport path
during scanning.
• Note that the ISIS/TWAIN driver has a Deskew function that can
detect a skewed document from the scanned image, and straighten
it.
Staple Detection Function
When sensors at both sides of the feed inlet detect the bent corner of
a stapled document, an error message appears and feeding stops.
IMPORTANT
• Staple detection detects the bent corner that occurs when one of
the four corners of a document has been stapled.
• Staple detection may not operate properly in the following cases
where bending does not occur in documents.
– The document is stapled at two or more corners.
– The document is size smaller than STMT/A5.
– The position of the left or right document guide has been
changed, and the document has been shifted to the left or right
side. (See "Adjusting the Document Guides" on p. 42.)
• Be careful to keep the staple detection window glass clean, and
wipe the glass if dust is present.
Hint
• Staple detection is controlled in the ISIS/TWAIN driver, and the
detection level can be set in the User Mode.
Level Setting" on p. 80.)
• Staple detection for the Count-Only mode can be set in the User
Mode. (See "Staple Detection Setting" on p. 79.)
Selectable Background
You can specify whether the background behind the scanned image
is black or white.
The background is changed by rotating the platen rollers to expose
either the black or white part of the rollers, according to the selection
specified in the ISIS/TWAIN driver.
