You can change the scanning resolution from the
Resolution
pop-up menu. Higher resolutions take more
memory and transfer time, but produce a finer scanned image. The following table shows the resolutions you
can choose and the available colors.

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

gray.
