Set [Suppress Background] and [Contrast].
Suppress Background
• Off
Scans document backgrounds with no filtering.
• Auto Suppression
When [Output Color] is set to [Black & White], the background of a document printed
on colored paper, such as newspaper, will be suppressed.
When [Output Color] is set to [Color], [Dual Color], or [Single Color], the color element
on white-color paper such as the blot, the print on the other side which is seen through
and so on will be suppressed.
Note • When [Output Color] is set to [Color], you can change the level of background suppression. For more
information, refer to"Background Suppression (Photo & Text)" (P.322) and "Background Suppression
Level (Text)" (P.322).
Contrast
• Auto Contrast
Automatically adjusts the brightness and hue of the original document to sharpen the
image.
Note • [Auto Contrast] is not available when you use the document feeder.
• Manual Contrast
Allows you to select from the five levels between [More] and [Less].
Selecting an upper cell on the bar makes the difference between light and dark areas
greater; light areas become lighter and dark areas darker. In contrast, selecting a lower cell
on the bar makes the difference between light and dark areas smaller.
Color Effects (Selecting an Image Quality)
If you set this feature, the [Image Enhancement], [Image Options], [Color Shift], and
[Color Balance] settings are automatically adjusted and copies are made at the specified
quality.
Note •
When the Color Effects feature is used, [Auto Contrast] is not available.
• If other image-quality settings are made after you set [Color Effects], the setting made in [Color
Effects] will be cleared.
