Adjusting Gradation

If color gradation reproducibility has become so poor that the gradation in the printed or copied image differs markedly from the print data or original document, gradation adjustment may improve the problem. There are two types of adjustments: Full Adjustment and Quick Adjustment.


Adjustments may not be performed effectively if there is not sufficient toner. Checking the Toner Level

Full Adjustment

Correct the gradation of an image accurately and optimize reproducibility during printing. Optimized information will be retained until the next accurate correction.

Press

<Auto Adjust Gradation>.

Select the paper to adjust, and press <Full Adjust>.

If you selected <Simple> in <Adjustment Level>, it is not necessary to select the paper. Adjustment is applied to all paper types.

Changing the Settings for Adjustment

Select the paper source in which the paper you selected in step 2 is loaded, and press <OK>.

Press <Start Printing>.

A test page is printed.

The test page refers to a sheet of paper with four color stripes printed, which you use in the following steps.

Place the test page on the platen glass.

Place the test page sheet in the machine in a manner that its side on which the four color stripes are printed faces down and the black stripe faces toward the back side of the machine.

Close the feeder and press <Start Scanning>.

The machine starts scanning the test page.

Open the feeder, and remove the test page.

Repeat steps 4 to 7.

To complete the adjustment, print the test page four times, and scan it each time it is printed.

Quick Adjustment

This adjustment maintains the optimized status that was acquired by <Full Adjust>. If the result of this adjustment is not satisfactory, perform <Full Adjust>.

Press

<Auto Adjust Gradation>.

Select the paper to adjust, and press <Quick Adjust>.

If you selected <Simple> in <Adjustment Level>, it is not necessary to select the paper. Adjustment is applied to all paper types.

If the room environment dramatically changes after registering the adjustment paper, the gradation, density, and color may not be able to be correctly adjusted by performing auto gradation adjustment using the registered adjustment paper. In this case, register the adjustment paper again. Since this may cause poor color balance, make sure to perform auto gradation adjustment (full adjustment) after changing the settings.
