You are using Adobe® Photoshop® 2.5.1 and the Color Drawing and Color Halftone options are grayed out in the Image Type
This is because Photoshop 2.5.1 can scan only in 1, 8, or 24 bits per pixel, so you cannot use these
The Preview icon is grayed out when the Automatic Document Feeder is selected under Document Source.
The preview feature is disabled when the Automatic Document Feeder is selected because the document would have to be fed through the feeder for the preview scan and then reinserted into the feeder for the final scan. If necessary, use the document table for previewing your document.
