Paper guidelines
Paper characteristics
The following paper characteristics affect print quality and reliability. Consider these factors before printing on them:
Weight
The printer trays and multipurpose feeder can automatically feed paper weights between 60–176 g/m
2
(16–47‑lb) grain
long paper. The 2100‑sheet tray can automatically feed paper weights up to 60–135 g/m
2
(16–36‑lb) grain long paper.
Paper lighter than 60 g/m
2
(16 lb) might not be stiff enough to feed properly, and may cause jams.
Note: Two‑sided printing is supported for 60–176 g/m
2
(16–47‑lb) 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.
Smoothness
Paper smoothness directly affects print quality. If paper is too rough, toner cannot fuse to it properly. If paper is too
smooth, it can cause paper feeding or print quality issues. Always use paper between 100 and 300 Sheffield points;
smoothness between 150 and 250 Sheffield points produces the best print quality.
