Image Quality > Original Type
The Original Type feature provides a convenient way to enhance the quality of your
output based on the type of original images you are copying. Select the Original Type
button on the Image Quality tab, and select the desired option.
Auto
This option sets the output color according to the document type preset in the System
Administration mode.
Photo and Text
Use this option if your original is from a magazine or other source that contains high
quality photographs with text. This setting produces better pictures, but slightly reduces
sharpness for text and line art.
Text
Use this option if your original contains only text or line art. The result is sharper edges
for the text and line art.
Photo
This option is specifically designed to copy photographs or magazine pictures without
any text or line drawings. This option prevents faint reproduction of colors.
Map
Use this option for making copies of documents that have text on colored backgrounds
such as maps.
Image Quality > Image Options
Use the Image Options feature to make adjustments to the following options:
Lighten/Darken
This option provides manual control to adjust the lightness or darkness of the scanned
images. Select the Down scroll button to darken the scanned image from light originals
such as pencil images. Select the Up scroll button to lighten the scanned image from
dark originals such as half tones or originals with colored backgrounds.
Sharpness
This option controls the balance between sharp text and moiré (patterns within the
image). Move the slider control down (Soften) to produce an image with a smooth,
uniform appearance (ideally suited for photographic scanned images). Move the slider
control up (Sharpen) to produce an image with better quality text or line art.
Saturation
This option allows colors to become more or less vivid. To make the colors on your
output more vivid, move the slide bar up. To create a less vivid output, or a pastel effect,
move the slide bar down. To keep the output normal, do not adjust the saturation.
