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.

  • When Integrated Color Care Unit IQ-501 is not mounted on the machine with Relay Unit RU-518 mounted, make adjustments using Relay Unit RU-518.

This section describes how to make adjustments using Relay Unit RU-518 when the Integrated Color Care Unit IQ-501 is not mounted on the machine.

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

  • When Relay Unit RU-518 is mounted, this button is displayed, enabling you to configure settings.

  • Be sure to use the paper for registering a desired density to perform Max. Density Auto Adj. (RU). 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. (RU), 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. Follow the procedure on Displaying the [Administrator Setting Menu] Screen to display the Administrator Setting Menu screen.

  2. Press System Setting on the Administrator Setting Menu screen, and then press Expert Adjustment, Process Adjustment, and Max. Density Auto Adj. 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.

    The charts are measured using the density sensor of Relay Unit RU-518 and delivered into the output tray.

    • supplementary explanationYou cannot stop the adjustment until all charts (four charts in total) 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 Measured Value for each color.)

  8. Press Return to return to the Process 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.
