• Originals are scanned according to the size of paper placed on the Paper Feed Tray when masters are made; for
the same width, the positions of the Feed Tray Paper Guides.
When the placed paper is smaller than an original, not the entire original will be scanned.
When the placed paper is larger than an original, dirt on the glass or shade of the original, for example, may result
in unexpected dirt in the area beyond the size of the original.
• Bound originals can also be used on the Stage Glass.
• You can feed automatically up to 50 original sheets when using the optional ADF (Auto Document Feeder) unit.
Note:
• Use the Stage Glass when printing the following originals:
– Patched or worn originals
– Wrinkled, curled, folded, or torn originals
– Transparent originals (such as tracing paper or OHP transparencies)
– Chemically treated originals (such as thermal or carbon paper)
– Originals with correction fluid or glue
– Extremely thin originals (less than 15-lb bond (50 g/m
– Extremely thick originals (greater than 34-lb bond (128 g/m
– Heavy drawing paper
– Originals with staples or clips
• If an original is wrinkled, curled, or creased flatten it thoroughly so that the originals can be pressed directly onto
the Stage Glass during processing.
• If correction fluid or glue is used on an original, thoroughly dry it before placement.
• For an original patched with thick paper, the shade of the patched paper may also be printed.
