For detailed information, refer to the Card Stock & Label Guide
located on the Drivers, MarkVision and Utilities CD.
The following paper characteristics affect print quality and reliability.
We recommend that you keep these guidelines in mind when evalu-
ating new paper stock.
Weight The printer can automatically feed paper weights from 60 to
131 g/m
2 (16 to 35 lb bond) grain long. Paper lighter than 60 g/m 2
(16 lb) might not be stiff enough to feed properly, causing paper
jams. For best performance, use 75 g/m
2 (20 lb bond) grain long
paper. If you 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
2 (24 lb bond).
Curl Curl is the tendency of paper to curve at its edges. If curl is exces-
sive, 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.
Smoothness 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.
