Paper guidelines
Use the appropriate paper to prevent jams and help ensure trouble‑free printing.
•
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.
•
Do not use paper that has been cut or trimmed by hand.
•
Do not mix paper sizes, types, or weights in the same tray; mixing results in jams.
•
Do not use coated papers unless they are specifically designed for electrophotographic printing.
Paper characteristics
The following paper characteristics affect print quality and reliability. Consider these factors before printing on
them.
Weight
Trays can feed paper of varying weights. Paper lighter than 60 g/m
properly, and may cause jams. For more information, see the "Supported paper weights" topic.
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 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 issues. We recommend the use of paper with 50
Sheffield points.
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. Exposure of paper to moisture changes can degrade its
performance.
Before printing, store paper in its original wrapper for 24 to 48 hours. The environment in which the paper is
stored must be the same as the printer . 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.
Printer status
The printer is in Deep Sleep or Hibernate mode.
