surface underneath, called the platen. At the edges of the glass you'll see guide marks that indicate where to position your document. Once the document is in place, lower the cover. If the photocopier has a document feeder instead of a cover over the platen, do not lift the document feeder off the platen. Instead place your document in the document feeder. Usually you will insert the document face up. Look at your document feeder. “Place document face up” or “Place document face down” will often be noted directly on the document feeder.
