Weight
The printer can automatically feed paper weights from 60–176 g/m
2
(16–47 lb bond) grain long. Paper lighter
than 60 g/m
2
(16 lb) might not be stiff enough to feed properly, and may cause paper jams. For best performance,
use 75 g/m
2
(20 lb bond) grain long paper. For paper smaller than 182 x 257 mm (7.2 x 10.1 inches), we recommend
90 g/m
2
(24 lb) 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.
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 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.
For 60–176 g/m
2
(16–47 lb bond) paper, grain long paper is recommended. For paper heavier than 176 g/m
2
,
grain short 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.
For detailed information on paper with recycled fiber content, see “Using recycled paper and other office
papers” on page 33 .
Selecting paper
Using appropriate paper prevents jams and helps ensure trouble
‑
free printing.
To help avoid jams and poor print quality:
•
Always use new, undamaged paper.
•
Before loading paper, know the recommended print side of the paper. This information is usually indicated
on the paper package.
