Adjusts the background density of an image.
Adjust the image quality by pressing [Lighter] or [Darker].
Press [OK].
Adjustments should be made lighter when copying dark textured originals, such as newspaper or recycled paper.
Adjustments should be made darker when darkening the color of markers or highlighters. However, as the color of highlighters is difficult to reproduce, the copy might not come out depending on the color or a different color might be copied.
