Maximum Density Adjustment (Regular Adjustment Flow (High Accuracy))

To improve fluctuations in the density, adjust the maximum density.

• Image quality adjustment flow and the position of this adjustment

  • In the pre-output image quality adjustment flow, this adjustment is positioned shown below.

  • Perform the previous adjustment before proceeding with this adjustment.

  • When Integrated Color Care Unit IQ-501 is mounted on the machine, this adjustment is positioned in the same way as the above.

(STEP 4: Color density control)

  1. On the control panel of the main body, press Utility/Counter.

    The [UTILITY] screen is displayed.

  2. Press [Administrator Setting].

  3. Press [System Setting].

  4. Press [Expert Adjustment].

  5. Press [Process Adjustment].

  6. Press [Maximum Density Adjustment].

  7. Adjust the maximum density for each color of [<Yellow>], [<Magenta>], [<Cyan>], and [<Black>].

    • If Relay Unit RU-509 is not mounted, go to step 10 after adjusting the density.

    • When the measured density is lower than the target density (target value): Adjust the density toward the + side (darker).

    • When the measured density is higher than the target density (target value): Adjust the density toward the - side (lighter)

    • The amount of the density change differs depending on the type of paper. Repeat the adjustment to achieve your most desired density.

    • Density Measurement Result (Rough Value), [Measurement History], and [Print Mode] are displayed only when Relay Unit RU-509 is mounted.

    • If Relay Unit RU-509 is not mounted, you need to measure the density with an external spectrophotometer (densitometer) and manage the measurement data.

  8. Press [Print Mode] to print the chart.

    Density Measurement Result is displayed in the lower right of the [Maximum Density Adjustment] screen.

    • Press [Measurement History] to view the measurement history (up to 30 results).
      Press [Switch Display] on the [Maximum Density Measurement History] screen to sort the list in order of the measurement date and the paper type.

  9. Repeat steps 7 and 8 until the desired result is obtained.

  10. Press [OK] to complete the setting.

  11. When [UTILITY] is exited, the gamma automatic adjustment starts. Wait for the adjustment to finish.
