If your scanner has an ADF, select Scan double-sided pages in the Scanner tab of the Options dialog box to scan pages that have text on both sides. You will be prompted to turn the stack over.
If your scanner does not have an ADF, select Automatically scan pages in the Scanner tab of the Options dialog box, and select the number of seconds you want OmniPage Pro to wait before scanning the next page in the Time between scans box. Be sure to give yourself enough time to add the next page to your scanner.
Otherwise, click the Additional button in the AutoOCR toolbar or the Document Source button in the Manual toolbar to load or scan each additional page.
Create and use a zone template if all pages have similar layouts. See Creating and Using Zone Templates for more information.
