Sub Area | You can define a brightness level and dither setting for a specific area |
| of an image that is different from the brightness level and dither setting |
| of the whole image. |
| This way, a picture can be dithered while the rest of the page remains |
| undithered, or a faint stamp can be enhanced by setting a lower |
| brightness than the rest of the page. You can define three regions per |
| side. Each region can have its own brightness level, but all regions |
| must use the same dither setting. |
| Each scanning side is settable for up to three regions. This function is |
| available only for Binary mode. |
