2.1. Selecting paper

2.1.1. Paper guidelines

Use appropriate paper to prevent paper jam and ensure trouble-free printing.
• It is recommended to use new, undamaged paper.
• Before loading paper, know the recommended printable side of the paper. This information is
usually indicated on the paper package.
• Do not use paper that has been cut or trimmed by hand.
• Do not mix paper sizes, types, or weights in the same tray; mixed use can cause paper jams.
• Do not use coated paper unless they are specifically designed for electrophotographic printing.

2.1.2. Paper characteristics

The following paper characteristics affect print quality and reliability. Consider these factors before
printing.
Weight
The tray can feed grain long paper with a weight of 60-200 g/m2. Paper lighter than 60 g/m2 may
not be stiff enough to feed properly, and may cause paper jams.
Curl
Curl is the tendency of 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 unpacked in hot, humid, cold, or dry conditions can contribute to paper
curling before 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 problems.
Moisture content
The amount of moisture in paper affects both print quality and the printer ability to feed the paper
correctly. Leave paper in its original wrapper until you use it. Change in the moisture content caused
by paper exposure 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 60-200 g/m2
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, leading to fewer paper feeding problems
and better print quality. Paper containing fibers such as cotton can negatively affect paper handling.
