by adding toned shades of gray in regions between black and

white. The copy modes are described in the table below:

2d-sharpening, 2d-softening, and 2d-blur

Through your software, you can manually set and control

sharpening, softening, and blurring filters, giving you rich

possibilities for combining effects to obtain perfect enhancement

results.

For example, you may have an image with details (such as text or

lines) you wish to sharpen. But if the image also contains large

concentrated areas of colors or graytones, sharpening will make

unwanted noise to appear in the scanned image. By using the

sharpen filter together with the blur filter, you can get the sharp

edges you need without creating the side effect of unwanted noise.

Both filters can be set at different levels for ultimate control of effects.

The B/W Copy Normal scanning mode incorporates 2D-Auto edge

enhancement, with automatic, on-the-fly sharpening of your image.
