Automatic Gradation Adjustment

You can recalibrate the machine when you notice irregularities in the colour of the copies or prints, such as when copies turn out to be different from the original in gradation or density.
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.
Automatic gradation adjustment may differ, depending on the optional equipment attached to the machine.
If the Color Image Reader Unit-E1 is not attached, internal adjustments are made to the gradation and density settings for the image without outputting any test pages.
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.
Auto Adjust Gradation appears in the following situations:
If the Color Image Reader Unit-E1 is attached.
If the PS Printer Kit is activated.
NOTE
Test pages are not counted as part of the copy or print total page counts.
