This option is used to improve the scan quality on some Nikon and HP scanners.
When using the Nikon CoolScan 5000 (LS-5000), CoolScan 8000 (LS-8000) or CoolScan 9000 (LS-9000), this option causes only one CCD line to be used, which makes scans take longer but sometimes improves the scan quality of very dark media.
When using some HP printer/scanners/copiers, this option disables in-scanner JPEG compression of scans, which makes scans take longer but sometimes improves the scan quality by eliminating subtle JPEG artifacts.
Advanced Option: This option is displayed with some Nikon and HP scanners..
