SymptomCauses and solutions

After you start calibration, the following message appears:
Communication error - try unplugging and replugging EyeOne

Confirm that the measuring device is connected. Firmly
plug it into the computer. Do not plug it into the USB
connector on the keyboard.

If the message still appears, the measuring devices may
be damaged. Try another measuring device.

After you start calibration, the following message appears: Calibration failed. Please check if the EyeOne is connected.

And the logs show: Calibration failed : New integration time: No light.

  1. Make sure that the shutter on the calibration plaque was open to expose the white tile when you "zero" the measuring device.

  2. Do not use Active USB Extension/Repeater cables when connecting the measuring device to the computer.

You start the calibration, but the monitor does not calibrate successfully, or one of the following messages appear:

  • Unable to setup monitor according to vendor instructions.
  • Error setting up display pixels for accurate color.


  1. Ensure that the monitor's image data cable and USB control cable are securely connected.

  2. Ensure that the measuring device cable is securely connected.

  3. Check the fixed luminance setting. The monitor may be unable to achieve the set value. If so, lower the setting and recalibrate.
    Note: Replace the monitor when it can no longer achieve a luminance level of 120.

  4. Ensure that you "zero" the measuring device on its calibration plate. Any light leakage will cause problems.
    Note: If you use the iOne Display 3, you do not need to perform the "zero" step.

  5. Check the measuring device for damage. If it is damaged, try a different measuring device.

The monitors can no longer calibrate.Calibrate all monitors to maximum luminance and use the lowest maximum luminance value as the reference point for setting a new fixed luminance.

You start the calibration using the iOne Display 3 colorimeter and the following message appears:

Calibration failed
New integration time: Too little light

To perform a successful calibration, make sure that the cover of the colorimeter is open.
After you start calibration, the following message appears: The black measurement has drifted too much - must recalibrate measurement device

This message might appear due to any of the following:

  • The EyeOne Pro colorimeter is not seated perfectly in the calibration plaque during the black calibration performed at the beginning.
  • The EyeOne Pro is older than Rev B or is malfunctioning.
  • Long waiting times have been encountered during the calibration process.

 Solution

  1. Quit the MVCalibrator application.
  2. At the Dock, click the Matchprint Virtual folder icon.
  3. Select MVCalibrator and in the MV Calibrate window that appears, on the right-hand side, click Image.
  4. Make a note of the Fixed Luminance value and any changes that you made to the White Point. 
  5. Switch to Max luminance. Click Save.
  6. Immediately switch back to the Fixed Luminance value and enter the value that you recorded. Click Save.
  7. If you are using multiple monitors, select the other monitor in the Calibrator settings window and perform steps 5 and 6 for it.
  8. Click Calibrate to start over.
    Note: After you calibrate successfully, if you need to adjust the white point, re-enter the values for it.  

You start the calibration using the iOne Pro colorimeter and the following message appears:

White calculation: Sensor is saturated.

To perform a successful calibration, make sure that you open the protective slider until it clicks into place to access the white reference ceramic tile on the calibration plate.

You start calibration and the following message appears:

Monitor not allowing white point to be set.

If you are using a NEC UHD type monitor, the video signal might not be set properly.

Solution: 

  1. Check the video level setting on the display and set to expand if necessary. 
  2. Verify that the DV Mode is standard and the color mode is Programmable.
