If the original document consists of several pages and all of the thumbnail images cannot be displayed at once, you may use the Holding Area to temporarily hold images while you use the scroll bars to move to another part of the document.
Thumbnails of pages that have been moved to the Holding Area are displayed, but dimmed, in the Separation Workspace to indicate that the page is currently in the Holding Area.
Note:
Depending on your system's configuration, the Holding Area may not be displayed.
