Decurler Setup and Decurler E Table Settings
When paper is exposed to heat, the paper loses moisture and
curls toward the heat source. High toner coverage jobs tend to
curl more due to the toner plastification effect on the paper
surface. The system tries to reduce this by using mechanical
devices within the paper path called decurlers.
Your system has been designed with an automatic curl control
system that uses information such as: the amount of coverage on
the page, paper weight, whether the paper is coated or uncoated,
and the current humidity and temperature to determine the
amount of pressure needed at the different decurlers to reduce
output curl.
With some print jobs, the output prints still may be curled more
than you desire. In cases like these, use the Decurler Setup and
Decurler E Table Settings features to compensate for paper curl in
your prints.
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
