Settings in the Scanner window

Resolution

You can change the 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.

Resolution	Black & White/	256 Color	True Gray/24bit Color
	Gray (Error Diffusion)
100 x 100 dpi	Yes	Yes	Yes
150 x 150 dpi	Yes	Yes	Yes
200 x 200 dpi	Yes	Yes	Yes
300 x 300 dpi	Yes	Yes	Yes
400 x 400 dpi	Yes	Yes	Yes
600 x 600 dpi	Yes	Yes	Yes
1200 x 1200 dpi	Yes	No	Yes
2400 x 2400 dpi	Yes	No	Yes
4800 x 4800 dpi	Yes	No	Yes

Scan Type

Black & White

Use for text or line art images.

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 gray appearance.)

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.

24bit Color

Uses up to 16.8 million colors to scan the image.

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