摘要： Embodiments herein observe the backing of the document handler to determine if a document was left on the platen and would block the scan head from scanning the documents as they are moved by the document handler. An embodiment herein comprises a transparent platen and a document handler on a first side of the platen. The document handler has a backing, and the backing is adapted to move media within the document handler. A scan head is positioned on a second side of the platen. The scan head remains stationary when scanning the media being moved by the document handler and the scan head moves when scanning media on the platen. The backing of the document handler has a surface that is distinguishable from the media such that the scan head can detect whether the media is on the platen and would block the scan head from scanning the media being moved by the document handler.
摘要翻译：本文中的实施例观察文档处理器的背景，以确定文档是否留在压板上，并且当文档被文档处理器移动时将阻止扫描头扫描文档。本文的实施例包括在压板的第一侧上的透明压板和文件处理器。文档处理程序具有后台，并且后台适于在文档处理程序中移动介质。扫描头位于压板的第二侧。当扫描由文件处理器移动的介质时，扫描头保持静止，并且当扫描台上扫描介质时扫描头移动。文档处理器的背景具有与介质可区分的表面，使得扫描头可以检测介质是否在压板上，并且将阻止扫描头扫描由文档处理器移动的介质。
