This filter typically provides better JPEG compression than the standard E - Edge Sharpen command (see page 8-15). This filter also works well when shipping pure black and white images (1 bit per pixel). The optimal setting is 26U.

0U Document image filter off (default)

26U Apply document image filter for typical document image

nU Apply document image filter using grayscale threshold n. Use lower numbers when the image contrast is lower. 1U will have a similar effect to setting E - Edge Sharpen (page 8-7)to 22e.

Range: 0-255.
