Scanning from TWAIN and WIA

Bayer dither scan - Close up

Mixed Content Options (Text and Graphics)

The Bit depth reduction list includes automatic separation options for mixed content documents containing both text and graphics. These options enable the scanner to evaluate the image for text and graphics, and then apply threshold to the text regions and a dither pattern to the graphics regions. This retains text clarity while providing graphic legibility.

The mixed content options are:

Threshold – Diffusion

Threshold – Bayer

Threshold – Halftone

The size of the hole can be between approximately 4 mm and 12 mm

The maximum width of the margin is 25.4 mm from the edge of the paper

The size of the margin is 24.4 mm
