Although I'm not an expert (or close), because no one else seems to have answered, I'll give it a shot (and am hopeful that I'll be corrected if I'm wrong). "RAW" is a general term for a variety of formats (different for every camera brand) that capture all information a camera sensor receives without in-camera processing (for white balance, sharpening, etc.) A scanner works differently from a camera sensor, and I don't believe that RAW is an option. To get high-quality images from a scanner, scan to TIFF at high ppi, but be careful because files can become huge (and thus difficult to manage) and you might consider adjusting scan ppi to match the size of the print you intend to make, adjusting the scan ppi to about 300 dpi for the print.
