degrees of the leading edge of the document. Deskew can detect up
to a 45-degree skew and correct up to a 24-degree angle at 200 dpi
or a 10-degree skew angle at 300 dpi. This option is not available
when Fixed to Transport or Relative to Document is selected.
NOTE: To prevent data loss, the document must have all four
corners within the image path.
• Halftone Removal  enhances images containing dot matrix text
and/or images with shaded or colored backgrounds using halftone
screens and effectively eliminates noise caused by the halftone
screen.
