Scanning

Resolution

You can choose a scanning resolution from the Resolution drop-down list. Higher resolutions take more memory and transfer time, but produce a finer scanned image. The following table shows the resolutions you can choose and the available colors.

Scan Type

„Black & White

Use for text or line art.

„Gray (Error Diffusion)

Use for photographic images or graphics. (Error Diffusion is a method for creating simulated gray images without using true gray dots. Black dots are put in a specific pattern to give the appearance of gray.)

„True Gray

Use for photographic images or graphics. This mode is more exact because it uses up to 256 shades of gray.

„256 Color

Uses up to 256 colors to scan the image.

„24 bit Color

Uses up to 16.8 million colors to scan the image.

Although using 24 bit Color creates an image with the most accurate color, the image file will be about three times larger than a file created with 256 Color. It requires the most memory and has the longest transfer time.

Reduce Noise

You can reduce noise of scanned images. When noise appears in scanned images or prints of the scanned image, this setting can reduce the noise.
