Epson Expression 636 User Manual - TWAIN 32 - Page 39

The following table identifies the options available with each Pixel Depth setting. Since both the Draft & fast and Best & de-screening Quality options are available with all the Pixel Depth settings, the table does not include these options. The table also does not include the Text Enhancement Technology and Auto Area Segmentation options; these are available only when Pixel Depth is set to Black & White.
