Max. Density Auto Adj.

The Maximum Density Auto Adjustment is :

  • When Integrated Color Care Unit IQ-501 is provided, the density is automatically adjusted using Integrated Color Care Unit IQ-501.

  • Integrated Color Care Unit IQ-501 is not provided, the density is adjusted using Relay Unit RU-518.

This section describes how to make adjustments using Relay Unit RU-518 without Integrated Color Care Unit IQ-501.

Automatically adjust the maximum density for each of Y, M, C, and K colors by scanning printed charts with the color sensor density mounted on Relay Unit RU-518.

NOTICE

  • Be sure to use the paper for registering a desired density to perform Max. Density Auto Adj.. With an unregistered paper, the adjustment cannot be performed correctly.

  • If you want to perform automatic adjustment using paper other than a registered paper, you need to register a desired density again. For details, contact your service representative.

  • When this adjustment is conducted, proceed to the calibration with the Image controller.

  • Be sure to perform Color Density Manual Control after changing the maximum density.

Tips

  • After Max. Density Auto Adj., the paper profile used for automatic adjustment changes to the one used for registering a desired density; the profile does not return to the one before adjustment. You can ask a service engineer to specify the setting so that after this adjustment the paper profile automatically returns to the one before adjustment. For details, contact your service representative.

  • When Integrated Color Care Unit IQ-501 is mounted, Maximum Density Auto Adjustment is displayed. When Integrated Color Care Unit IQ-501 is not mounted, Max. Density Auto Adj. (RU) is displayed.

  • This adjustment is not displayed when this machine is not equipped with Relay Unit RU-518 without Integrated Color Care Unit IQ-501.

  1. Press Adjustment on the MACHINE screen to display the Adjustment Menu screen.

  2. Press Quality Adjustment and Max. Density Auto Adj. (RU) in sequence.

  3. Press Print Mode.

  4. Load paper used to register a desired density in a tray

    The paper profile for the tray automatically changes to the one used for registering a desired density.

  5. Select a tray into which paper is loaded, and press OK.

  6. Press Start on the control panel.

    A chart applied the Screen 1 (Dot190 Recommended) is Output.

    Charts are processed by colorimetry, and delivered to the output tray.

    • supplementary explanationYou cannot stop the adjustment until all charts are completely printed.

  7. When adjustment is completed, the display automatically returns to the Maximum Density Auto Adjustment screen.

    The measurement result is displayed in After Adjustment.

    The automatically adjusted result is displayed in Current Data. This value is applied to Maximum Density Adjustment.

    • supplementary explanationPress Measurement History to view the measurement history (up to 30 results).

    • supplementary explanationPress Switch Display on the Maximum Density Measurement History screen to change the items in the history list. (Display 1: Measurement Date and Measured Value for each color, Display 2: Paper Type and Set Value for each color.)

  8. Press Return to return to the Quality Adjustment Menu screen.

    Note that the paper profile for the tray remains in the one used for registering a desired density.

    • supplementary explanationWhen you want to make fine-adjustment after checking the result of the automatic adjustment, manually make adjustments using the Maximum Density Adjustment in the section above.
