About Documents
The DR-5020/5080C can feed a wide variety of document sizes. The ranges of
width and length for a document as follows:
Width : 55 to 297 mm (2.2 to 11.7 in.)
(The actual maximum scanning width is 295 mm/11.6 in..)
Length : 70 to 432 mm (2.8 to 17.0 in.)
Thickness : 0.06 to 0.15 mm
(at manual feed: 0.06 to 0.2 mm)
Follow these guidelines when you prepare a document for scanning.
• Before scanning documents that contain pasted artwork, make sure that the ink
or paste on the pages is thoroughly dry. If the documents are scanned with ink
or paste still wet, the inside of the scanner may become dirty.
• If you scan a document written in pencil, the letters may disappear as the
document is fed through the scanner or graphite from the surface of the
document may transfer to and stain the scanning rollers. Before you scan these
kind of documents, make a copy and then scan the copy. After scanning a
document written in pencil or some other soft writing materials, be sure to clean
the scanning rollers (P.83).
• If you scan thin paper in the Duplex mode, ink printed on one side may be
legible on the other side. If this happens, adjust the scan density.
• If you scan a slippery surface document, friction may cause a feed error to
occur. If this happens, slide the paper feed adjustment lever (P.32) to adjust
paper feed.
• To avoid paper jams, damage to documents and scanner malfunction, do not
feed the following types of paper into the scanner. If you want to scan these
types of paper, first make a copy on a copier and the scan the copy.
Paper with clips or staples
Carbon-backed paper
Coated paper or fax recording paper
Onion skin or other thin paper
Paper with binding holes
Wrinkled or creased paper
Curled paper
Torn paper
