Max. Density Auto Adj.: Automatically Adjusting the Maximum Density for Y, M, C, and K

The Maximum Density Auto Adjustment is :

  • When Integrated Color Care Unit IQ-501 is mounted on the machine, automatic adjustment is made using Integrated Color Care Unit IQ-501.

  • When Integrated Color Care Unit IQ-501 is not mounted on the machine with Relay Unit RU-509 mounted, make adjustments using Relay Unit RU-509.

This section describes how to make adjustments using Relay Unit RU-509 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-509.

  • When Relay Unit RU-509 is mounted, this button is displayed and can be set.

  • To activate this function, you need to ask a service engineer in advance to set up the desired maximum density value (desired density). For details, contact your service representative.

  • 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.

  • 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 on the machine, [Max. Density Auto Adj.] is displayed. When Integrated Color Care Unit IQ-501 is not mounted on the machine, [Max. Density Auto Adj. (RU)] is displayed.

  • When neither Integrated Color Care Unit IQ-501 nor Relay Unit RU-509 is mounted on the machine, this adjustment is not displayed.

  1. Follow the procedure on Administrator Setting 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. (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 the tray in which you load paper, and then 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-509 and delivered into the output tray.

    • You cannot stop the adjustment until all charts (four charts in total) are completely printed.

  7. After the adjustment is completed, the screen returns to the [Maximum Density Auto Adjustment (RU)] screen.

    The measurement result will be displayed on [After Adjustment].

    The result of automatic adjustment is displayed under [Current Data]. These values are reflected on Maximum Density Adjustment: Adjusting the Maximum Density for Y, M, C, and K.

    • Press [Measurement History] to view the measurement history (up to 30 results).

    • Press [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 [Process Adjustment Menu] screen.

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

    • To perform the fine adjustment after checking the result of automatic adjustment, manually adjust each item in [Max. Density Auto Adj.].
