This troubleshooting guide is for dentists, dental assistants, laboratory technicians, and digital workflow managers who need a practical first response when a dental scanner behaves unexpectedly.<\/strong> Start by identifying whether the problem comes from the scanner tip, the scan environment, the computer connection, the software, or the case file. Work through one change at a time so the cause is easier to isolate.<\/p>\n

How to Diagnose a Dental Scanner Problem<\/h2>\n
    \n
  1. Identify the stage:<\/strong> note whether the issue appears during startup, scanning, processing, export, or file transfer.<\/li>\n
  2. Record the conditions:<\/strong> include the scanner model, tip, software version, operating system, case type, and the exact error message.<\/li>\n
  3. Check the simplest causes first:<\/strong> inspect the tip, cable, USB connection, field moisture, storage, and software status.<\/li>\n
  4. Reproduce safely:<\/strong> test a compatible tip, case, or computer only when the user manual allows it, and keep the original case file.<\/li>\n
  5. Escalate with evidence:<\/strong> send support the recorded conditions and a screenshot or short video when the issue continues.<\/li>\n<\/ol>\n

    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

    1. Scanner lens fogging during scanning<\/h2>\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

      \n
    1. Wait for the scanning software to complete the handpiece preheating cycle.<\/li>\n
    2. Check that the scanner tip is installed correctly and that the heating contacts are clean and undamaged.<\/li>\n
    3. Blow gently on the protective glass as a quick breath test. If the glass stays clear, resume scanning.<\/li>\n
    4. If fogging returns, clean and disinfect the tip according to the user manual and contact CEDU support<\/a> for a hardware check.<\/li>\n<\/ol>\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

      2. Scans are incomplete or missing margins<\/h2>\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
