SP 1-008 to 014: Density setup examples 

These values control the image density for the 7 settings on the operation panel. 
Here are three examples 
Case 1: There is a relatively small difference between the minimum and maximum 

settings 

Case 2: The higher values in this example make the image lighter. 
Case 3: The lower values in this example make the image darker.
