Paper Curl

Paper curl is a very significant factor in printer performance. It can affect the printer in

the following ways:

■ Paper jam, paper skew and ability to be picked up

■ Paper stacking uniformly in the output stacker

■ Paper wrinkles through the heat roller (fuser).

Nearly all paper has curl or a tendency to curl. Curl can occur after the paper passes

through the printer’s fuser where it is exposed to high temperatures. In most paper, curl

results from unusually large, sudden, or uneven changes in the moisture content.

How to Avoid Paper Curl

■ Use high-quality xerographic paper.

■ Store the paper in a moderate environment (40% to 60% relative humidity).

■ Minimize humidity changes throughout the day in the printer room.

■ Minimize the humidity difference between the paper storage area and the printer

room. If the humidity difference is considerable, move the paper into the printer

room a few days before to allow the paper to adjust to the printer room

environment.

■ Wrap the unused paper properly in moisture-resistant wrappers to protect the

paper from moisture absorption or loss.
