The CMOS sensor is like the film in a film camera. If any dust or other foreign matter adheres to the CMOS sensor, it may show up as a dark speck in the pictures you take. To avoid this, follow the procedure below to clean the CMOS sensor. Note that the CMOS sensor is very delicate. If possible, you should have it cleaned by a Canon Service Center. When you want to clean the CMOS sensor, use the DC Coupler Kit to power the camera with a household power outlet. If you use the battery, make sure it is fully charged.
Before cleaning the sensor, detach the lens from the camera.

6. Exit the sensor cleaning.
- Turn the <> to <OFF>.
- The camera will turn off, the shutter will close, and the mirror will go back down.

- Be sure not to turn off the camera while cleaning the CMOS sensor. If the power is turned off, the shutter will close and the shutter curtains might be damaged.
- Use a blower not attached with a brush. The brush can scratch the CMOS sensor.
- Do not insert the blower tip inside the camera beyond the lens mount. If the power goes out, the shutter curtains will close and the blower tip may damage then.
- 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.
