Solution
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. If the amount remaining in a toner cartridge is low, it is recommended that you replace toner cartridges. For details, see the "e-Manual" (HTML manual) in the DVD-ROM supplied with the machine. 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 cartridge remaining.
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.
