As media enters the Interface Module, it is fed to the
Decurler for curl correction. The Decurler has both
upper and lower decurl rolls that apply pressure to
the media based upon the following:
• System default
• Decurl selections made in tools-mode on the

• Manual selections made at the Decurler

device
Based on the decurl settings, the Decurler Gate
routes the paper either to the up-curl
(Upward/Cupped) path or to the down-curl
(Downward/Bridged) path. Pressure then is applied
to the paper to remove any upward or downward
curl. The paper is then moved from the decurler to
the connected finishing device.
When paper is exposed to heat, the paper loses
moisture and curls toward the heat source. High
coverage jobs tend to curl more due to the toner
plastification effect on the paper surface. The
system tries attempts to reduce this by using a
mechanical decurling device, located within the
Interface Module.
Some factors affecting paper curl are:
• The weight of the paper and/or whether it is
coated or uncoated.
• The amount of dry ink/toner and the area
being coverage per sheet.
• How the paper is loaded in the tray.
• The atmospheric conditions of the paper
storage room and at the printer location.
• The amount of heat generated during the
fusing processes.
If the curl is unacceptable, you can change the
setting.
