This section explains the differences between scanning mixed-size originals using the TWAIN scannerand normal scanning.
If [Auto detect (Mixed-size)] is selected in the [Original Size:] list, the machine detects the length of each original and then scans them.
If [Auto detect (Uni-size)] is selected in the [Original Size:] list, the machine detects the size of the first original of the batch and scans all subsequent originals at that size.
