Scanner Settings
 Scanner settings affect how pages are scanned, and thus can affect text 
recognition. To change scanner settings, choose Scanner Settings from 
the Settings menu. 
 Click on the Auto Threshold button (left of the Brightness slider bar) to 
enable automatic brightness; the word or percentage next to the 
brightness scroll bar will change to Auto
Image Type
Binary images include line art that are typically black lines on a white 
background. Choose Binary for scanning pages with text and line art. 
If your scanner supports dithering, you can choose Dithered for scanning 
pages of mixed half-tone images and text. A dithered pattern is an 
arrangement of black-and-white dots that simulates a half-tone. 
Different dither patterns produce extremely different results, and it is 
generally much coarser than a half-tone due to the limitation of scanning 
and printing at 300 dots per inch.
Page Size
Choose the input size of the page you are scanning. Select Letter to scan 
8 1/2” x 11” pages, Legal to scan 8 1/2” x 14” pages, or A4 to scan 21cm 
x 29.7cm pages.
