Cleaning the Image Sensor (CMOS)
The image sensor is like the film in a film-based 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. Use
the AC Adapter Kit ACK-E2 (optional accessory, see page 128) or a
battery. If you use a battery, make sure the battery level is sufficient.
Before cleaning the image sensor, detach the lens from the camera.
Insert the DC coupler (p.22) or a
fully charged battery into the
battery compartment and set the
Power switch to <1>.
