Overview: This article provides instructions for troubleshooting color and 3D calibration failures for Trios 3 and Trios 4 scanners in Chairside or Trios software.
Prerequisites
Identify if the failure is related to Color Calibration or 3D Calibration.
Verify the scanner model: Dandy Trios Wired, Trios 3, and 4 require weekly calibration. Trios 5 self-calibrates.
Note: Scanning does not need to be delayed if a patient is present; calibration can be completed 1–5 days after the recommended 7-day cycle without impacting scan quality.
Troubleshoot Color Calibration Failures
If color calibration fails, follow these steps to verify the scanner configuration:
Check Calibration Target: Confirm the correct side of the color calibration target faces the mirror in the scanner tip.
Check Mirror Tip: Ensure you are using a mirror tip rather than a protective tip.
Attempt Calibration
Replace Mirror Tip: If the error persists, request the practice use a new or unblemished mirror tip.
Reseat Adapter: Reconnect the color calibration adapter and ensure the color calibration target "clicks" into place.
Attempt Calibration: Restart the calibration process from the beginning after making these changes.
Troubleshoot 3D Calibration Failures
If 3D calibration fails, follow these steps to resolve configuration or hardware issues:
Reconnect Adapter: Remove and reconnect the 3D calibration adapter, ensuring a firm friction fit on the scanner neck.
Restart Software: Restart the Chairside or Trios software and begin the calibration again.
Use Alternative Target (B Side): If the 3D adapter fails, use the B side of the color calibration target. These tests are interchangeable as both perform a "grey surface" test.
