Adjusting Gradation

If 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.
You can use the following paper sizes/types.
Size: A4, LTR
Type: Plain, Heavy
Adjustments may not be performed effectively if there is not sufficient toner.
Press   <Adjustment/Maintenance> <Adjust Image Quality> <Auto Adjust Gradation>.
Select the paper source where plain paper or heavy paper is loaded, and press <OK>.
Press <Start Printing>.
A test page is printed.
The test page refers to a sheet of paper with black stripes printed, which you use in the following steps.
Place the test page on the platen glass.
Place the test page so that the side with the printed stripes is face down and the stripes on the page are located on the far 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 3 to 6.
To complete the adjustment, print the test page three times, and scan it each time it is printed.
