Paper characteristics
The following paper characteristics affect print quality and reliability. Consider these characteristics when
evaluating new paper stock.
•
Weight —The printer can automatically feed paper weights from 60 to 176 g/m
2
(16 to 47 lb bond) grain
long. Paper lighter than 75 g/m
2
(20 lb) might not be stiff enough to feed properly, causing jams. For best
performance, use 80 g/m
2
(21 lb bond) grain long paper. For paper smaller than 182 x 257 mm (7.2 x 10.1
in.), we recommend 90 g/m
2
or heavier paper.
•
Curl —Curl is the tendency for paper to curl at its edges. Excessive curl can cause paper feeding
problems. Curl can occur after the paper passes through the printer, where it is exposed to high
temperatures. Storing paper unwrapped in hot, humid, cold, or dry conditions, even in the trays, can
contribute to paper curling prior to printing and can cause feeding problems.
