The award winning M4097D scanner is based on the fi-4750L, but adds additional speed and ADF capacity. The fi-4750L can scan in monochrome or grayscale at speeds up to 55 pages per minute (ppm) simplex and 100 images per minute (ipm) duplex. The fi-4750L features a 250-page automatic document feeder that can be continuously fed for maximum throughput. The dual CCD camera array uses 1024 level internal grayscale to deliver superior image detail. The scanner offers standard image processing including error diffusion, dynamic thresholding and image emphasis. For more advanced image processing or functionality, Fujitsu's ScanRight IPC or VRS technology can be purchased as an option.
