Troubleshooting Steps

Step 1: Turn the scanner off and on.

Step 2: Check that the USB connection meets the requirements detailed in the article "USB connection requirements for 3Shape lab scanners".

Step 3: Try another USB port.

Step 4: Replace the scanner's USB cable. For an F8 scanner, replace the Ethernet cable.

Step 5: Connect the scanner to a different PC and check whether the issue is reproduced there.

Step 6: Make sure the drivers are installed correctly and updated according to the article "How to find 3Shape lab scanner in Device Manager and update scanner's drivers".

Step 7: Review the recommendations in the article "What to consider when calibrating Lab Scanners". Make sure all recommendations are being followed, including the correct positioning of the calibration object.

Step 8: Make sure the plastic cover has been removed from the calibration object.

Step 9: Check that the calibration object (dot plate) is in good condition. Make sure there are no smudges, visible damage such as scratches, or stains and dirt. If possible, try using a different calibration object.
