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-E2 (optional, see page 154) is
recommended. If you use a battery, make sure the battery level is
sufficient. Before cleaning the sensor, detach the lens from the camera.

¡
During the sensor cleaning, never do any of the following that
would turn off the power. If the power is cut off, the shutter will
close and it may damage the shutter curtains and image sensor.
• Turn the <
4
> switch to <
2
>.
• Open the CF card slot cover.
• Open the battery compartment cover.
¡
Do not insert the blower tip inside the camera beyond the lens mount. If
the power goes out, the shutter will close and the shutter curtains and
image sensor may be damaged.
¡
Use a blower not attached with a brush. A brush can scratch the sensor.
¡
Never use canned air or gas to clean the sensor. The blowing force can
damage the sensor or the spray gas can freeze on the sensor.

When the battery is exhausted, the beeper will sound and the <

You cannot clean the sensor if Battery Grip BG-E2 (optional) is attached
to the camera and size-AA batteries supply the power. Use AC Adapter
Kit ACK-E2 (optional) or use a battery having sufficient power.
