SELECTING A PROPER IMAGE 

TYPE 

 

Select image type through the mode from 

the scanner user interface for your own purpose.     
 
Each image type is described as follows: 
 

Line art(Black and White) 

 

 
 

LineArt presents the image in black and white only 
and there are no intermediate shades of gray in 
between.    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.

 

         

       

 

 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.
