Reduce/Enlarge
This feature allows an image to be automatically enlarged or reduced as it is
scanned. The default scaling factor is 100%. The selected scaling factor
affects size of the printed scan output. This feature is available when the
scanned image type is set to one of the color choices or to Gray 256 scales.
Note: When scanning a printed image for screen display only, scale the
image down to increase processing speed and decrease the file size.
