Solution
If dust adheres to the image sensor and dust spots appear on the images, you can clean the image sensor yourself with a commercially-available camera blower.
Caution
The image sensor is extremely delicate. If the sensor needs to be cleaned directly, it is advisable to contact a Canon Service Center.
If you use a battery, make sure it is fully charged.
For the power source, using DC Coupler DR-E10 (sold separately) and Compact Power Adapter CA-PS700 (sold separately) is recommended.

Caution
While cleaning the sensor, never do any of the following. If the power is cut off, the shutter will close and the shutter curtains and image sensor may get damaged.
- Setting the power switch to ⋖OFF⋗.
- Opening the card slot/battery compartment cover.
The surface of the image sensor is extremely delicate. Clean the sensor with care.
Use a plain blower without any brush attached. A brush can scratch the sensor.
Do not insert the blower tip inside the camera beyond the lens mount. If the power is turned off, the shutter will close and the shutter curtains or reflex mirror may get damaged.
Never use pressurized air or gas to clean the sensor. Pressurized air may damage the sensor, and sprayed gas may freeze on the sensor and scratch it.
If the battery level becomes low while cleaning the sensor, the beeper will sound as a warning. Stop cleaning the sensor.
If a smudge that cannot be removed with a blower remains, having the sensor cleaned by a Canon Service Center is recommended.
