Please read 

 the Decurler information before using 

the Decurler E Table Settings (E1 - E6) procedure.
When paper is exposed to heat, the paper loses moisture and 

curls toward the heat source. High toner coverage jobs tend to 

curl more than low toner coverage jobs. The system tries to 

reduce this by using mechanical devices within the paper path 

called Decurlers.
Paper curl is caused by many variables, including, but not in any 

particular order:
•

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.

•

How the paper is loaded in the tray. Make sure you load the 

paper as instructed on the ream wrapper.

•

The atmospheric conditions of the room where the paper is 

stored and where the printer is located, especially those 

related to humidity and temperature.

•

The heat generated during the fusing processes.

Your system is designed with several automated settings to 

control curl. When using these settings the machine automatically 

sends paper through the proper Decurler:
•

System Default: Automatically determines the amount of 

pressure needed at the different decurlers in order to reduce 

the output curl of the paper.

•

Paper Type A, B, C, and D settings: Preset Decurler settings, 

which are manually selected as an alternative to the System 

Default setting. 

KEY POINT: While paper curl is caused by many variables, it is 
important to understand that the preset and custom Decurler 
profile settings use lookup tables for curl control that are based on 
the job’s percentage of toner area coverage and the printer’s 
humidity values, only.
