Adjusting 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. There are two options of gradation adjustment: "Full Adjust" for accurate adjustment, "Quick Adjust" for simple adjustment.

Adjustments may not be performed effectively if there is not sufficient toner cartridge remaining. Check the amount of toner remaining in each cartridge. If the amount of toner is low in any of the toner cartridges, it is recommended that you replace the toner cartridge(s). Checking the Remaining Amount of Consumables |
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. To make a full adjustment, repeat the operation, "print out the adjustment image and scan it," multiple times. Note that you cannot perform this adjustment while performing some functions, including, scanning, and printing.

If the printed color tones are different from the color tones of the print dataDepending 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. |
