Scan Using the Control Panel Setting Description Applicable Feature Image OCR E-mail File Resolution Select a scanning resolution from the Resolution Yes Yes Yes Yes drop-down list. Higher resolutions take more memory and transfer time, but produce a finer scanned image. Scan Type Select from a range of scan color depth. Yes Yes Yes Yes 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. 7 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. Auto Uses suitable colors for your document automatically. Document Size Document size is set to Auto by default. You can scan Yes Yes Yes Yes documents of any size without making adjustments to Document Size. For faster scan speeds, select the exact size of your document from the Document Size drop-down list. NOTE • If you select a 1 to 2 document size, the scanned image will be divided into two documents that are half the size of the setting. If you select 1 to 2(A4), the scanned image will be divided into two A5-size documents. • To do 1 to 2 scanning, clear the Auto Image Rotation check box in the Advanced Settings dialog box. • If you select a 2 in 1 document size, two scanned images will be combined into one document. 193
