Setting Original Orientation on the TWAIN Scanner

To correctly display the top/bottom orientation of the scanned original on a client computer, the placement of the original and the settings made in the Scanner Control dialog box must match.

Open the Scanner Control dialog box.
For details about how to open the Scanner Control dialog box, see "Basic Network TWAIN Scanner Operation".
Make settings in the [Original Size] area.

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

How to place originals

Top edge of original is placed first Align the original, turn it rightward or leftward, and then place it face down.	Off
Top edge of original is on the right Align the original so that its top edge is on your left, turn it rightward or leftward, and then place it face down.	Right 90 deg.

Bottom edge of original is placed first Align the original, turn it rightward or leftward, and then place it face down.	180 deg.

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.
