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.

Full Adjustment

Correct the gradation of an image accurately and optimize reproducibility during printing. Optimized information will be retained until the next accurate correction.
You can use the following paper sizes/types.
Size: A3, A4, 11x17, LTR
Type: Plain, Heavy 1, Heavy 2 to 7
