Using Paper
Basis Weight
Basis weight is an important characteristic to consider because, paper that is too light or too
heavy may cause misfeeds, mis-stacking, paper jams, or excessive mechanical wear.
The printer is specifically designed to perform at maximum efficiency when 20 pound bond
(75g/m
2
) paper is used. Optimum print quality and paper path reliability are achieved when
high quality electrophotographic (EP) paper is used. EP papers have specific characteristics
that distinguish them from bond papers. The range of paper weight that the printer and HCI can
process is 17 to 24 pound (64 to 90 g/m
2
). The printer can handle paper weights up to 36
pound (135 g/m
2
), but 17 to 24 is optimum.
Specifications for basis weight depend upon the paper source the paper is fed. In general, the
straighter the paper path, the heavier the basis weight may be. For more complex paper paths,
as in feeding from the HCI, a lighter weight may be required, in range of 18 to 24 pound.
Furnish (Composition)
Furnish is the fiber and chemical composition of paper. Fiber composition of the paper used in
D640 printers should be manufactured from 100 percent chemical wood pulp and/or cotton
fiber. To ensure that paper of a special fiber composition will work properly, always test it
before purchasing large quantities. Other allowable components of paper are sizing, fillers,
buffers and pigments.
Note DO NOT use coated paper or paper containing materials that melt, vaporize, offset,
discolor or release hazardous emissions when exposed to 392°F (200°C).
