Troubleshooting: Code 19 Error in Device Manager

If your MouthWatch camera is showing a Code 19 error in Device Manager, this is typically caused by a conflicting camera driver installed by third-party imaging software on your PC. Following the steps below should resolve the issue.

Step 1: Uninstall the Conflicting Driver

Open Programs and Features (Windows 10) or Installed Apps (Windows 11)
Look for an application called CeflaHD in the list
If found, uninstall it
Restart your PC

Step 2: Confirm the Issue Is Resolved

After restarting, test your MouthWatch camera. Unplug and replug it to confirm the Code 19 error does not return. If the error is gone and stays gone, no further action is needed.

Step 3: If the Error Returns After Restart

If the Code 19 error comes back after restarting, the CeflaHD driver is likely being reinstalled automatically by another program on your PC.

Open Programs and Features (Windows 10) or Installed Apps (Windows 11) again
Look for iCapture or any NewTom imaging software in the list
If found, uninstall it or disable it from startup
Uninstall CeflaHD again, then restart your PC

Step 4: If the Issue Persists

If the driver continues to reinstall after completing the steps above, contact your NewTom or Cefla imaging software's support team and request assistance fully removing the conflicting camera driver. An updated driver compatible with Windows 11 may be available through them.

Note:
If your office uses NewTom or Cefla products alongside your MouthWatch camera, their support team will be best equipped to assist with managing their software's driver components.
