Detecting Skewed Documents

This scanner includes a function that can detect when a document has
been fed at a slant. When this function is used, the scanner will stop a
scanning operation automatically when it detects a skewed document
that exceeds a fixed angle, thereby preventing damage to the
document. In addition to skewed documents, this function also detects
stapled documents.
This function is useful for documents that are 170 mm (6.7") or larger
in width.
To use the skew detection function, open the scanner driver settings
screen and enable the skew detection function beforehand.
