The Document Scan Lock mode does not guarantee restriction of unauthorized copying. You may not be able to restrict unauthorized copying or analyze tracking information, depending on the combination of settings and the output, such as a document with an image on the entire page.

Use STMT size or larger. Do not use paper with a low whiteness level, such as colored paper. Do not use paper with high transparency, such as thin paper or transparencies. Make sure to use the correct paper size and type to effectively use the Scan Lock Information and Tracking Information. (See "Available Paper Stock.")
