USEFUL FUNCTIONS Changing compression ratio You can select the compression ratio for the scanned image data. In general, the higher the compression ratio, the lower 1 the image quality. Select from the following options: [SINGLE] - Select this option to scan only the front of the originals. [BOOK] - Select this option to scan both sides of the originals in the same direction. [TABLET] - Select this option to scan the front in one direction and the back rotated by 180 degrees. Specifying original size To specify the original size, press [ORIGINAL SIZE]. Pressing the button displays the buttons for selectable original sizes along with the following buttons: 2 [LOW] - Select this option to apply a low compression ratio and enhance the image quality. [MID] - Select this option to compress the data with a 3 moderate compression ratio and obtain an average image quality. [HIGH] - Select this option for a high compression ratio. This option is suitable when you want to minimize the data size rather than enhance the image quality. Note • The compression ratio setting is not available in either of the 4 following conditions: - [SLIM PDF] is selected as the file format setting. - [BLACK] is selected as the color mode setting.

To take advantage of this feature, enable 5 the Omit Blank Page setting. 6 [AUTO] - Select this option to have the equipment automatically detect the size of your originals.
