5—Paper and specialty media guide
Paper guidelines
Selecting the correct paper or specialty media reduces printing problems. For the best print quality, try a
sample of the paper or specialty media before buying large quantities.
Paper characteristics
The following paper characteristics affect print quality and reliability. Consider these characteristics when
evaluating new paper stock.
Weight
The standard printer trays can automatically feed paper weights up to 90-g/m
2
(24-lb) bond grain long
paper. The optional trays can automatically feed paper weights up to 120-g/m
2
(32-lb) bond grain long
paper. The multipurpose feeder can automatically feed paper weights up to 163-g/m
2
(43-lb) bond grain
long paper. Paper lighter than 60 g/m
2
(16 lb) might not be stiff enough to feed properly, causing 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), it is recommended to use 90 g/m
2
(24 lb) or heavier paper.
Note:
Two-sided printing is supported only for 60–90-g/m
2
(16–24-lb) bond 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 150–250 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.
Condition paper before printing by storing it in its original wrapper in the same environment as the printer
for 24–48 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.
