Dental scanners improve digital impressions and laboratory workflows, but small setup or maintenance issues can affect scan quality and turnaround time. This guide explains common dental scanner problems, practical first checks, and when to contact technical support.<\/p>\n
Lens fogging is usually related to the scanner tip not reaching its preheating state or to a problem with the heating contact. Pause the scan and work through these checks:<\/p>\n
For a detailed checklist, see How to prevent intraoral scanner lens fogging<\/a>. These steps are also relevant to the OScan intraoral scanner<\/a>.<\/p>\n Incomplete scan data can come from insufficient isolation, excessive saliva, movement, or an inconsistent scanning path. Dry the field, improve retraction, and scan slowly across the occlusal, buccal, and lingual surfaces. Keep a short overlap with the previous scan so the software can track the new data.<\/p>\n When a dental scanner is not detected, start with the connection path rather than reinstalling everything. Confirm that the scanner is connected to the correct USB port, inspect the cable for damage, and restart the scanning software. If the scanner uses a hub or adapter, connect it directly to the computer for testing.<\/p>\n Also check whether another scanning application is using the device. Close duplicate software sessions, restart the computer, and confirm that the scanner driver and application version are compatible.<\/p>\n If installation stops or shows an error, download the latest complete installation package for the scanner and confirm that the download finished successfully. Run the installer from a local folder with a Windows account that has permission to install applications.<\/p>\n For the full procedure, read How to fix dental scanner software installation failure<\/a>.<\/p>\n Tracking can become unstable when the scanner moves too quickly, the field contains too few recognizable features, or the scan has gaps. Slow down, return to the last stable area, and add new data with short overlapping movements. Avoid jumping from one surface to another without a transition.<\/p>\n For a laboratory desktop scanner, keep the model stable and remove reflective contamination before scanning. A consistent setup helps a QScan desktop dental scanner<\/a> maintain reliable data capture.<\/p>\n Noise may be caused by moisture, reflective surfaces, a dirty protective glass, or an incorrect scan path. Clean the scanner tip using the approved method, dry the field, and check the model or preparation before rescanning. Do not use abrasive materials or unapproved chemicals on the optical surface.<\/p>\n Compare the scan with the physical model or clinical situation before designing. If the same area repeatedly produces inaccurate data, record the scanner model, tip, software version, and conditions so support can reproduce the issue.<\/p>\n Before exporting, confirm that the case has finished processing and that the destination folder is available. Use a short, consistent file name and verify that the exported file opens correctly before sending it to the laboratory or CAD\/CAM software.<\/p>\n Contact technical support when the same fault returns after the basic checks, when the scanner is not detected on more than one compatible computer, when heating or calibration appears abnormal, or when scan accuracy changes suddenly. Include the scanner model, software version, operating system, error message, and a short video or screenshot whenever possible.<\/p>\n CEDU provides scanner and digital dentistry support for clinics and laboratories.
