4. Adjust the scan settings that you want.
Mode—Select Black/White to scan in black and white.
For example, letters and memos are usually scanned in black and
white. Select Grayscale to scan items such as documents containing
drawings or black and white photographs. The scanning produces
an image in varying shades of gray. Select Color to scan color
photographs and other color items.
Resolution—Drag the slider to the right or left to adjust the dots
per inch (dpi) of the resolution. The maximum resolution is
600 dpi; the minimum is 50 dpi. The higher the dpi setting, the
sharper and clearer the scanned image. However, higher dpi settings
take longer to scan and produce larger files for the scanned images.
Brightness and Contrast—Drag the sliders to the right or left to
adjust the brightness and contrast of the scanned image.
The Contrast setting does not apply to the Black/White mode.
