Scan Type Black & White: Set the Scan Type to Black & White for text or line art. Gray Scale: Set the Scan Type to Gray (Error Diffusion) or True Gray for photographic images. Colours: Set either: 256 Colour, which scans up to 256 colours, or 24 bit Colour which scans up to 16.8 million colours. Although using 24 bit Colour creates an image with the most accurate colours, the image file will be approximately three times larger than a file created with 256 Colour. Brightness Adjust the setting (-50 to 50) to obtain the best image. The default value is 0, representing an 'average'. You can set the level by dragging the slide bar to the right or left to lighten or darken the image. You can also type a value in the box for the setting. If the scanned image is too light, set a lower brightness value and scan the document again. If the image is too dark, set a higher brightness value and scan the document again. The Brightness setting is only available when Black & White or Gray is selected. Contrast This setting is only adjustable when you have selected one of the gray scale settings. It is not available when Black & White and Colour settings are selected as the Scan Type. You can increase or decrease the contrast level by moving the slide bar to the left or right. An increase emphasizes dark and light areas of the image, while a decrease reveals more detail in gray areas. You can also type a value in the box for the setting. HOW TO SCAN USING WINDOWS® 2 - 17
