Paper curl is caused by many variables, including:
• The manufacturer’s brand of paper and the manufacturing lot
• The weight of the paper and whether it is coated or uncoated
• The amount of dry ink/toner and the area being covered on a
sheet: the heavier the coverage, the greater the tendency to
curl
• The atmospheric conditions of the room where the paper is
stored
• The atmospheric conditions of the room where the digital
press is located
• The heat generated during the fusing processes
The digital press is equipped with an automatic curl control system
that uses the variables listed above to determine the amount of
pressure needed at the different decurlers in order to reduce the
curl.
Decurler specifications
The Decurler has both top and bottom adjustment arms that apply
pressure to the paper based on system defaults, selections made
on the Tray Properties screen, or based on selections made on
the Decurler Profile screen. The degree of pressure is applied
independently to the top and bottom Decurler arms.
