Cleaning the CMOS sensor N

The image sensor is like the film in a film camera.If any dust or other foreign matter adheres to the image sensor, it may show up as a dark speck in the images. To avoid this, follow the procedure below to clean the image sensor. Note that the image sensor is a very delicate component. If possible, you should have it cleaned by a Canon Service

Center.

While you clean the image sensor, the camera must be turned on.

Using the AC Adapter Kit ACK-DC20 (optional, see page 158) is recommended. If you use a battery, make sure the battery level is sufficient. Before cleaning the sensor, detach the lens from the camera.

¡ You cannot clean the sensor if Battery Grip BG-E3 (optional) is attached to the camera and size-AA batteries supply the power. Use AC Adapter

Kit ACK-DC20 (optional) or use a battery having sufficient power.
