NARA says "Improve Your Image" The National Archives and Records Administration (NARA) has published higher standards for scanning resolution, which better support archival preservation. Threfore, the Administrative Office of the United States Courts is asking courts and attorneys to use scanner settings of 300 pixels per inch (ppi) or higher. Courts are asked to increase the maximum CM/ECF file size setting by 25% to allow for higher scanning settings without requiring additional splitting of filed documents.  ¶ 2:57 PM
