When Printed Colors Appear Differently

If certain printed colors appear too bright or are different from the colors in the original, perform [Color Calibration] in [Settings][Printer Settings][Data Management/Maintenance][Image Adjustment] to adjust the color balance.

Note

  • If you have not used the machine for a long time, the printed colors may have changed.

  • If you feel the calibrated color is not appropriate, repeat the calibration several times as needed.

  • Color Calibration settings apply to all user jobs.

  • Use the same type of paper to print color calibration test sheet 1 and color calibration test sheet 2. If you use different types of paper, color calibration cannot be performed correctly.

  • This feature requires the color calibration sample sheet provided with the machine.

Perform Color Calibration in the following procedure.

  1. Perform Adjust Auto Density.

  2. Print color calibration test sheet 1.

  3. Adjust the highlights.

    1. Set the calibration values.

    2. Print the color calibration test sheet, and then check the result of the calibration.

  4. Print color calibration test sheet 2.

  5. Adjust the mid tones.

    1. Set the calibration values.

    2. Print the color calibration test sheet, and then check the result of the calibration.

  6. Save the calibration values.


How to Use Color Calibration Sample Sheet and Color Calibration Test Sheet

The color calibration sample sheet contains two color samples: Sample 1 for adjusting highlights and sample 2 for adjusting mid tones.

There are two types of the color calibration test sheets: Color calibration test sheet 1 for adjusting highlights and color calibration test sheet 2 for adjusting mid tones. the color calibration test sheet 1 is used for calibration 1, and the color calibration test sheet 2 is used for calibration 2.

How to use color samples on the color calibration sample sheet and calibration numbers of the color calibration test sheet

For C/Y, (Cyan) and (Yellow), the calibration number is determined with the two colors combined, but it is set one color at a time.

Compare the calibration numbers (0 to 6) for "K" on the color calibration test sheet and the color calibration sample 1 on the color calibration sample sheet, and then, on the control panel, enter the number of the closest color.

How to use color calibration test sheet

Compare the color calibration test sheet and the color calibration sample sheet to confirm the calibration numbers for each color, and then specify the calibration numbers on the control panel.

Illustration of color calibration test sheet

  1. K (black) calibration numbers
    Used to adjust the color printed when only black toner is used. The currently set calibration number is printed in red.

  2. M (magenta) calibration numbers
    Used to adjust the color printed when only magenta toner is used. The currently set calibration number is printed in red.

  3. C (cyan)/Y (yellow) calibration numbers
    Used to adjust the colors printed when only cyan and yellow toner are used. The cyan and yellow samples are printed on the sheet as the mixed color of cyan and yellow, but the settings are specified for each color.

  4. Setting value
    Displays the current calibration numbers for each color. The numbers are the same as the numbers set on the control panel.

  3. Press [Data Management/Maintenance][Image Adjustment][Color Calibration][Adjust Auto Density].

  4. Press [Start].

  5. After performing adjust auto density, press [Color Calibration 1][Print Calib. Pattern 1].

  6. Press [Start].
    The color calibration test sheet 1 will be printed.

  7. Compare the color calibration sample sheet and the color calibration test sheet to confirm the calibration number for each color.

  8. Press the color you want to adjust.

  9. Enter the calibration number and then, press [OK].
    You can enter a calibration number from 0 to 6.
    Perform the same procedure to set the other colors.

  10. After entering the calibration number, press [Print Calib. Pattern 1][Start].

  11. Compare the color calibration sample sheet and the color calibration test sheet to check the adjustment results.
    If you feel the adjusted color is not appropriate, repeat the procedure from step 8.

  12. Press [Color Calibration 2][Print Calib. Pattern 2].

  13. Press [Start].
    The color calibration test sheet 2 will be printed
    Perform the same procedure as step 7 to 11 to set [Color Calibration 2].

  14. After completing the procedure, press [Home] (Operation panel screen illustration) .
