Scan Type Set the image Type to Black & White for text or line art. For photographic images, set the image type to Gray (Error Diffusion) or True Gray. Gray (Error Diffusion) is used for documents that contain photographic images or graphics. (Error Diffusion is a method for creating simulated gray images by placing black dots in a specific matrix instead of true gray dots.) True Gray mode is used for documents containing photographic images or graphics. This mode requires the most memory and longest transfer time. Brightness Adjusting the brightness settings to obtain the best image. The MFC Software Suite offers 100 brightness settings (-50 to 50). The default value is 0, representing an "average" setting. You can set the brightness level by dragging the slidebar to the right to lighten the image or to the left to darken the image. You can also type a value in the box to set the settings. 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. Contrast The contrast setting is adjustable only when you have selected one of the Scan Type settings, but it is not available when Black & White is selected as the Scan Type. Increasing the contrast level (by dragging the slidebar to the right) emphasizes dark and light areas of the Image, while decreasing the contrast level (by dragging the slidebar to the left) reveals more detail in gray areas. Instead of using the slidebar, you can type a value in the box to set the contrast. Custom Size Set the Size to one of the following: N Letter (8 1/2 x 11 inches) N A4 (210 x 297 mm) N Legal (8 1/2 x 14 inches) N A5 (148 x 210 mm) N B5 (182 x 257 mm) N Executive (7 1/4 x 10 1/2 inches) N Business Card (60 x 90 mm) N Custom (User adjustable from 0.35 x 0.35 inches to 8.5 x 14 inches) After you select a custom size, you can adjust the scanning area further by using the left mouse button to drag the dotted outline of the scanning area. This is required when you want to crop an image when scanning. Business Card Size To scan business cards, select the Business Card (60 x 90 mm) size setting and place the business card at the top centre of a carrier sheet. When scanning photographs or other images for use in a word processor or other graphics application, you should try different settings for the contrast, mode and resolution to see which settings best suit your needs. 98 Chapter 14
