Solution
If dust cannot be removed from the sensor (CMOS) with the camera's sensor cleaning function, or if your camera does not have a sensor cleaning function, you can use a commercially-available blower to remove the dust manually.
IMPORTANT
The image sensor is extremely delicate. If the sensor needs to be cleaned directly, having it done by a Canon Service Center is recommended.
