Scan Using Your Computer TWAIN Driver Settings 6 1 2 3 4 6 5 6 (The Brother TWAIN screen supports languages specified in TWAIN-compliant application you use.) 1 Resolution Select a scanning resolution from the Resolution pop-up menu. Higher resolutions take more memory and transfer time, but produce a finer scanned image. 2 Scan Type Select one of the following:  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 grayscale images without using true gray dots. Black dots are put in a specific pattern to give a gray appearance.)  True Gray Use for photographic images or graphics. This mode is more exact due to using up to 256 shades of gray.  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, it requires the most memory and has the longest transfer time. 3 Document Size Document size is set to Letter by default. If you select Custom, specify the document size. 4 Adjust Image Click the Adjust Image button for adjusting the image. 125
