Maintenance Adjusting Gradation 3S1Y-0A1 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 adjustment (calibration). There are three types of adjustments: "Full Adjust" for accurate adjustment, "Quick Adjust" for simple adjustment, and "Adjust Copy Image" for gradation adjustment, especially for copying. Full Adjust(P. 622) Quick Adjust(P. 624) Adjust Copy Image(P. 624) ● Frequent calibration may affect the lifetime of toner cartridges. ● When the remaining amount of toner in cartridges is low, performing calibration may result in disruption of color balance. If this phenomenon actually occurs after calibration, it is recommended that you replace any toner cartridges of low remaining amount. Checking the Remaining Amount of Consumables(P. 618) ● The machine performs automatic adjustment (automatic calibration) in accordance with changes in the usage condition or environmental conditions. 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. 1 Select in the Home screen. Home Screen(P. 126) 2 Select . 3 Select . 622
