Placing originals

The following table shows the relationship between the original orientation and the Scanner Control dialog box settings:

Exposure Glass

Original Orientation	TWAIN Scanner Control Dialog Box Key
top edge touches top left of exposure glass This orientation is the TWAIN driver's standard setting. Place originals in this orientation normally.
top edge touches rear of exposure glass
bottom edge touches left side of exposure glass
bottom edge touches top of exposure glass

ADF

Original Orientation	TWAIN Scanner Control Dialog Box Key
top edge of original placed first
top edge touches rear of ADF
bottom edge touches left side of ADF
bottom edge touches top of ADF

Originals are normally rectangular () or horizontally long (). However, the table above uses squares to make original orientation easier to understand. 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.
Depending on the settings, originals of different sizes are scanned differently.
