Various Scan Settings
Note
❒ Originals are normally rectangular ( ) or horizontally long ( ). However,
the table above uses squares to make original orientation easier to under-
stand. Even if the actual shape of the original is different, the combination
of original orientation and the orientation specified on the scanner driver
does not change.
❒ For details about the Scanner Control dialog box, see the TWAIN driver
Help.
