• [Active Threshold] is intended for batch processing various kinds of
documents at once, such as those with thin (light) text or stains. For
example, you can batch process documents such as photocopies at
once. Brightness-related properties are automatically adjusted
based on the text and background of the whole image, enabling
consistent reproduction of light characters and removal of
background stains.
• [Detect automatically] detects whether the document is in color,
grayscale, or black and white. You can configure advanced settings
related to the detection method by clicking [Setting]. For details, see
the Help.

If [Match original size] is selected, the edges of the document are
detected and images that match the size of the document are saved.
Dots per inch
Select the scanning resolution.
• Higher resolutions provide clearer images but result in larger file
sizes and slower scanning.
• When [Detect automatically] is specified, the resolution is detected
automatically from the content printed in the document.
Scanning Side

If the scanning side is set to [Skip blank page], the images of blank
