    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. Before adjusting the gradation, check the remaining toner level. Gradation adjustments require significant toner (Replacing the Toner Cartridge).

    There are three types of auto adjustment.

    Full Adjust

    Precisely adjusts the gradation of colors to optimize reproducibility for color printing. The information for optimization will be stored in the machine until the next adjustment.

    Quick Adjust

    Briefly adjusts the gradation based on the information that was acquired by performing <Full Adjust>. This adjustment is sometimes performed automatically, such as when toner cartridges are replaced.

    Adjust Copy Image

    Use this adjustment to improve the quality of copies as well as printouts from a USB memory device.

    NOTE
    Adjustments may not be performed effectively if there is not sufficient toner.

    Making Full Adjustment

    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.

    NOTE
    • This adjustment requires significant toner. Make sure that the remaining toner is indicated as <OK> or <Low>.
    • This adjustment is not available when <Only Continue Black & White Printing> is selected on the screen displaying the message <End of Toner Cart. Lifetime>.

    NOTE
    If the <Correction failed.> message is displayed
    • Did you load plain or recycled A4 or Letter size paper in the paper drawer?
    • Did you place the adjustment image with the print side face down, with the black stripe toward the back side of the machine?
    • Has a paper jam occurred?
    • Is the amount of toner required for correction sufficient?
    • Is the transfer belt inside the machine dirty?

    Making Quick Adjustment
