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.
Caution
The image sensor is extremely delicate. If the sensor needs to be cleaned directly, having it done by a Canon Service Center is recommended.
Caution
For the power source, using DC Coupler DR-E6 (sold separately) and AC Adapter ACK-E6N (sold separately) is recommended. If you use a battery, make sure it is fully charged. If you use Battery Grip BG-E14 (sold separately) with AA/R6 batteries, manual sensor cleaning will not be possible.
