This mode enables you to scan and record the originals with a sharper or softer contrast. To reproduce text or lines with a sharper contrast, use [High] as the setting. To scan originals containing printed photographs or other halftones with a softer contrast, use [Low] as the setting.

• Low

If you scan an original containing halftones, such as a printed photograph, the moiré effect (a shimmering, wavy pattern) may occur. However, you can lessen this moiré effect by using [Low] as the setting to produce a clearer image.

• High

This setting enhances the edges of original images so that faint or fine text is reproduced with a sharper contrast. This setting is particularly suited to scanning blueprints and faint pencil drawn images.

• For information on the modes which cannot be set in combination with this mode, see "Combination of Functions Chart."

• As an example, the procedure for scanning an original and storing it in a mail box is explained in this section.

1. Select the desired Mail Box.

2. Place your originals → press [Scan].

3. Press [Options] → [Sharpness].

4. Press [Low], or [High] to adjust the sharpness → press [OK].

To scan text or lines clearly, the setting should be towards [High]. To scan originals containing printed photographs or other halftones, the setting should be towards [Low].

5. Press [Close].

6. Press (Start).
