Scanning

162

Settings in the Scanner window 9

Resolution 9

You can change the scanning resolution from the Resolution pop-up menu. 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 9

 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.

 8BitColor

Uses up to 256 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 colors reproduction, the image file

size will be about three times larger than a file created using the 8BitColor option. It requires the most

memory and has the longest transfer time.
