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.

The machine performs automatic adjustment (automatic calibration) in accordance with changes in the usage condition or environmental conditions. A certain amount of toner in toner cartridges is used when calibration is performed, whether it is initiated automatically or manually. 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 |
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)>*. To print on plain paper using the Superfine function, first perform correction with <Standard (Plain)>* and then with <For Printer 1200 dpi>*. * Perform correction using plain paper. |

If the <Could not perform correction.> message is displayedDid you load the paper displayed in step 5 into the paper source? 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? Clearing Paper Jams Is the amount remaining in toner cartridge required for correction sufficient? If the amount remaining in a toner cartridge is low, it is recommended that you replace toner cartridges. Checking the Remaining Amount of Consumables |
