Correcting the Gradation

Gradation refers to the dark to light continuum of shades of a color. The more shades in the gradations of colors that are printed, the more natural printouts seem. If color reproducibility becomes poor and the density and brightness of printouts differs markedly from the originals, perform the appropriate auto adjustment. Before adjusting the gradation, check the remaining toner level. Gradation adjustments require significant toner (Checking Toner Level). There are three types of adjustments: Full Adjust, Quick Adjust, and Adjust Copy Image.
Fewer shades in the gradations
 
More shades in the gradations
NOTE
Adjustments may not be performed effectively if there is not sufficient toner.

Full Adjust

This adjustment optimizes reproducibility for color printing. When the machine performs full adjustment, it obtains information to optimize color reproducibility. The machine maintains this information until the next time you perform full adjustment. For making full adjustment, an adjustment image will be printed twice and scanned twice. Note that you cannot perform this adjustment while performing some functions, including, scanning, and printing.
NOTE
This adjustment is not available when <Only Continue Black & White Printing> is selected on the screen displaying the message <End of Toner Cart. Lifetime>.
