Basic Operations 2. Press the Scan resolution button. The Quality dialog box appears: 3. Select from the following quality settings: ● Scan resolution: Manually set the scan resolution in dots per inch (dpi). ● Auto: The system determines the best scan resolution based on the print quality (Fast, Normal, or Best) that you select. The resolution setting (in dpi) is displayed next to the Auto checkbox (200 dpi in the example above). NOTE: The system determines the scan resolution based on the printquality that you select, however the print-quality setting is not actually used in the scan-to-network process. ● Descreen: The scanner scans with the optical resolution and relays the data to the system. The software then sets the optimal resolution value. NOTE: The Descreen setting gives the best results when scanning raster images (non-vector images, such as .jpeg, .tiff, and .pdf files), however the scanning speed is reduced. ● Turbo: The Turbo setting increases the rate at which the paper is fed and reduces the amount of scanning data that is captured, which means the scanning speed increases, but the image quality decreases. To use the Turbo setting, first manually set the scan resolution, and then select Turbo. NOTE: The turbo setting has no effect when the resolution is set below 300 dpi. 4. Press the OK button. 14 Chapter 2 Basic Operations
