Select a level of sharpness to make the document more legible.
Examples:
1. Photographic images in news papers or magazines
2. Blueprints or faint pencil-drawn originals
3. For more defined outlines of charts, graphs, photos
Low
If you make copies of an original containing half-tones, such as a printed
photograph using the Photo mode, screen clash may occur. However, by using
"Low," you can soften this moiré effect so that the copy is easier on the eyes.
High
This feature enhances the edges of original images so that the text is reproduced
more sharply. This is particularly suited to blueprints or faint pencil-drawn originals
