Decurler E Table Settings

While the system is programmed to correct for curl under most 
conditions, there may be instances where the pre programmed 
settings (System Default and Paper Type A - D) may not meet 
your curl requirements. Using the Decurler E Table Settings allows 
you to enter a percentage of toner area coverage range to help 
eliminate curl. 

NOTE: The examples that follow are designed to give you an 
understanding of programming the Decurler E Table Settings 
option to obtain optimal results, but due to various job stock and 
environmental conditions the manner in which you achieve the 
best results may vary. 

The most important aspect for creating Decurler E Table Settings 
is determining the percentage of toner area coverage on the 
curled paper. A sampling of percentage of toner area coverage on 
some typical customer documents follows.

NOTE: The following percentage of toner area coverage 
examples have been measured using the particular application’s 
tools which created them. If you do not have access to an 
application’s tools, which measure percentage of toner area 
coverage, make your estimate using the following examples as a 
guide. Your estimates will be used when entering 
Decurler E Table 
Settings values, which is explained later in this section.
