Using Print Materials
The paper characteristics defined below affect printing quality and
reliability. We recommend that you keep these guidelines in mind
when evaluating new paper stock.
The printer can automatically feed paper weights from 60 to
2
176 g/m (16 to 47 lb bond). Paper lighter than 60 g/m
not be stiff enough to feed properly, causing paper jams. For best
performance, use 75 g/m
want to print on print materials narrower than 182 x 257 mm (7.2 x
10.1 in.), the basis weight must be greater than or equal to 90 g/m
(24 lb bond).
Curl is the tendency of paper to curve at its edges. If curl is
excessive, it can cause paper feeding problems. Curl usually occurs
after the paper passes through the printer, where it is exposed to
high temperatures. Storing paper unwrapped in humid conditions,
even in the paper tray, can contribute to paper curling.
The degree of smoothness of paper directly affects print quality. If
the paper is too rough, the toner does not fuse to the paper
properly, resulting in poor print quality. If the paper is too smooth,
it can cause paper feeding problems in the printer. Smoothness
needs to be between 100 and 400 Sheffield points; however,
smoothness between 100 and 250 Sheffield points produces the
best print quality.
