	image. The resolution setting for a scan is in dots-per-inch (dpi). The

	also take longer to scan and produce larger files sizes. Usually the higher
	resolution settings are used for precision work, such as photographs or
	fine artwork.
	■ Click the Resolution drop-down menu and select the resolution for
	the item.
	The resolution settings on your Visioneer 9450 scanner range from
