Automatic Gradation Adjustment
When copying without using any special settings, if you notice irregularities in the gradation or density of the copy, you can calibrate the machine so that it adjusts to these irregularities.
This is a precise recalibration that is made to the gradation and density settings of the machine. The procedure involves making test pages and placing them on the platen glass for scanning. Once this is complete, the machine automatically corrects the irregularities.

IMPORTANT
|
|
Make sure that you place the test pages properly. Accurate recalibrations of the gradation and density settings of the machine cannot be made if the test pages are not scanned correctly.
Three test pages are output by the machine during this adjustment. This machine adjusts the toner and print speed according to the paper type. To make effective adjustments, select the correct paper type.
If Auto Adjust Gradation does not work well with heavy paper, print a test page with normal paper.
