Sharpness
Adjusts the sharpness of image outlines.
When copying penciled originals with rough or broken lines, clear copies can be taken by adjusting sharpness toward
"Sharpen". When copying images made up of patterned dots such as magazine photos, in which moire* patterns
appear, edge softening and weakening of the moire effect can be obtained by setting the sharpness toward "Blur".
When [All] is selected, press [-3] to [3] (Blur - Sharpen) to adjust the sharpness.
When [Text/Fine Line] is selected, press [0] to [3] (Normal - Sharpen) to adjust the sharpness.
* Patterns that are created by irregular distribution of halftone dots.
Background Density Adj.
Removes dark background from originals, such as newspapers. This feature is used with full color and auto color.

If the ground color is obtrusive, select [Auto]. If [Auto] does not remove the ground color, select [Manual] and adjust the
density of the ground color.
