■Size—Click Standard, click the menu arrow and choose a page size from the list, or click Custom and enter the horizontal and vertical page dimensions in the boxes. The maximum size is 8.5" by 11.69". The units of measurement can be inches or millimeters. Click the name of the units, inches or millimeters, to toggle between them.
■Improvements and Settings—Only the options that apply to the selected Destination Application are available.
Reduce Moire Patterns—Moire patterns are wavy, rippled lines that sometimes appear on the scanned images of photographs or illustrations, particularly newspaper and magazine illustrations. Selecting Reduce Moire Patterns will limit or eliminate moire patterns in the scanned image. This option is only available for the Grayscale or Color Mode at 300 dpi or less.
Straighten Image—Select this option to let the scanner automatically determine if a page is skewed on the glass, then straighten its image. The scanner detects page edges and can sense when the page is not straight. However, if the page is at too great an angle, the image may not straighten correctly. In that case, open the lid and reposition the page so it fits squarely on the glass, then re-scan the page.
Invert Image—Only available for Black&White Mode, this option reverses the black and whites of an image.
