2. Paper and paper trays
Curl
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 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.
If you are experiencing excessive curl, remove the paper from the
tray, turn it over and replace it in the tray. If the curl is still
excessive, refer to the System Administration Guide, Tools Mode
chapter, to change the decurler settings to accommodate the
environmental and paper conditions.
