Weight
The printer trays can automatically feed paper weights up to 176‑g/m
feeder can automatically feed paper weights up to 176‑g/m

60 g/m (16 lb) might not be stiff enough to feed properly, causing jams. For best performance, use 75‑g/m
bond grain long paper. For paper smaller than 182 x 257 mm (7.2 x 10.1 inches), we recommend 90 g/m
heavier paper.
Note: Duplex printing is supported from 60–105‑g/m
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, then toner cannot fuse to it properly. If paper is
too smooth, then 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.

Moisture content

The amount of moisture in paper affects both print quality and the ability of the printer to feed the paper correctly.
Leave paper in its original wrapper until it is time to use it. This limits the exposure of paper to moisture changes that
can degrade its performance.
Store paper in its original wrapper in the same environment as the printer for 24 to 48 hours before printing. Extend
the time to several days if the storage or transportation environment is very different from the printer environment.
Thick paper may also require a longer conditioning period.

Grain direction

Grain refers to the alignment of the paper fibers in a sheet of paper. Grain is either grain long, running the length of
the paper, or grain short, running the width of the paper.
2
For 60–90‑g/m (16–24‑lb) bond paper, grain long paper is recommended.

Fiber content

Most high‑quality xerographic paper is made from 100% chemically treated pulped wood. This content provides the
paper with a high degree of stability resulting in fewer paper feeding problems and better print quality. Paper containing
fibers such as cotton can negatively affect paper handling.

Selecting paper

Using the appropriate paper prevents jams and helps ensure trouble‑free printing.
To help avoid paper jams and poor print quality:
•
Always use new, undamaged paper.
• Before loading paper, know the recommended printable side of the paper. This information is usually indicated on
the paper package.
