Manual Sensor Cleaning


If dust adheres to the image sensor and dust spots appear on the images, you can clean the image sensor yourself with a commercially-available camera blower.
  • The image sensor is extremely delicate. If the sensor needs to be cleaned directly, it is advisable to contact a Canon Service Center.
  • If you use a battery, make sure it is fully charged.
  • For the power source, using DC Coupler DR-E10 (sold separately) and Compact Power Adapter CA-PS700 (sold separately) is recommended.

  • The procedure for changing the Sensor Cleaning is explained below.

1. Detach the lens before you start cleaning.

2. Set the power switch to <ON>.

3. Set the shooting mode to a Creative Zone mode.

4. Press the <MENU> button to bring up the menu display.

5. Select [ ] tab, [Clean manually], then press the < > button.

6. Select [OK], then press the < > button.

7. The reflex mirror will lockup and the shutter will open.

8. Using a commercially available blower, blow dust that is stuck to the surface while preventing the blower from directly touching the sensor.

9. End the cleaning.

10. Set the power switch to <OFF>.
  • While cleaning the sensor, never do any of the following. If the power is cut off, the shutter will close and the shutter curtains and image sensor may get damaged.
 - Setting the power switch to <OFF>.
 - Opening the card slot/battery compartment cover.
  • The surface of the image sensor is extremely delicate. Clean the sensor with care.
  • Use a plain blower without any brush attached. A brush can scratch the sensor.
  • Do not insert the blower tip inside the camera beyond the lens mount. If the power is turned off, the shutter will close and the shutter curtains or reflex mirror may get damaged.
  • Never use pressurized air or gas to clean the sensor. Pressurized air may damage the sensor, and sprayed gas may freeze on the sensor and scratch it.
  • If the battery level becomes low while cleaning the sensor, the beeper will sound as a warning. Stop cleaning the sensor.
  • If a smudge that cannot be removed with a blower remains, having the sensor cleaned by a Canon Service Center is recommended.
