and transfer time, but produce a finer scanned image.

Select one of the following type:
•Black & White

without using true gray dots. Black dots are put in a specific pattern to give a gray appearance.)
•True Gray

•256 Color
Use for simple color illustrations that do not use the full color spectrum. Uses up to 256 colors to create images.
