The image sensor is like the film in a film camera. If any dust adheres 
on the image sensor, it may show up as a dark speck on the images. To 
avoid this, follow the procedure below to clean the image sensor.
Using the AC Adapter Kit ACK-E2 (optional, see page 26, 184) is 
recommended. If you use a battery, make sure the battery level is 
sufficient. Before cleaning the sensor, detach the lens from the camera.
