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 Remaining 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.
You can use the following paper sizes/types.
Size: A3, A4, 11x17, LTR
Type: Thin, Plain, Recycled
If the printed color tones are different from the color tones of the print data
Depending on the paper to use for printing and the print settings, perform correction as follows.
To print on plain paper, perform correction with <Standard (Plain)>*1.
To print on heavy paper, first perform correction with <Standard (Plain)>*1 and then with <Standard (Heavy)>*2.
To print on plain paper using the Superfine function, first perform correction with <Standard (Plain)>*1 and then with <For Printer 1200 dpi>*1.
To print on heavy paper using the Superfine function, first perform correction with <Standard (Plain)>*1, then with <Standard (Heavy)>*2, and finally with<For Printer 1200 dpi>*2.
*1 Perform correction using plain paper.
*2 Perform correction using heavy paper.
