Resolution
Generally, the ideal scanning resolution is 150 dots per inch (dpi).
Changing the size of the image after you have scanned it affects
the resolution. Therefore, before you set the scanner resolution,
determine what the final image size will be. For example, you
might want to scan an original that is 76 x 127 mm (3 x 5 in.), but
there is only room for a 38 x 63.5 mm (1.5 x 2.5 in.) image in your
document. Set the scanner resolution to 75 dpi.
