SCANNER OPERATION For TWAIN Application AV600U allows you to operate the scanner from within a TWAIN or plug-in software application. As the scanner driver is not a standalone software, it has to be started from within a TWAIN/ISIS*compliant software application and then the scanner driver is able to scan and load the image to your computer. The command to start the scanner driver may vary due to different software applications. To check the correct command, please refer to the user manual of your software application. 4. 1 1. 2. USER INTERFACE OPERATION Open your TWAIN scanning application. Pull down the File menu and choose Select Source. If the Select Source command is not available on the File menu, see your application's user's guide to determine how the TWAIN link is used. A dialog box with a list of scanning sources appears. You need to select the source only once, unless you want to choose another scanner. That means each pixel of the image is 100% black or 100% white. LineArt is the best choice of image type if you want to scan text, pen or ink drawing. Since only 1-bit of black or white information is required for each pixel*, the disk space required for saving lineArt image is only about 1/24 of that required to save 24-bit true color images. 5-4 Lineart Image *Pixel: A combination of two words: picture and element, a pixel is a single dot on a computer display or in a digital image. 5-5 Halftone In addition to the black and white display, Halftone simulates gray scale by using different size of dots. Particularly when you view the image at a certain distance, it looks very closely like a gray image yet it consumes the least disk space. Halftone is the picture that we usually see in newspapers or magazines. Since Halftone is one type of black and white image, the disk space required to save a halftone image is 1/24 of that required to save a 24-bit true color image.
