Manual Sensor Cleaning (EOS 5D Mark IV)


Dust that could not be removed by the automatic sensor cleaning can be removed manually with a commercially-available blower, etc.
  • The image sensor is extremely delicate. If the sensor needs to be cleaned directly, having it done by a Canon Service Center is recommended.
  • If you will clean the sensor manually, make sure to use a fully-charged battery.
  • For the power source, using the household power outlet accessories (DC Coupler DR-E6 and AC Adapter AC-E6N; both sold separately,) is recommended.

1.Detach the lens from the camera before cleaning the sensor.

2.Set the power switch to <ON>.

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

4.Press the < > button, turn the < > dial and select the [ ] tab.

5.Turn the < > dial to select [Sensor cleaning], then press < >.

6. On the next screen select [Clean manually] and press < >.

7.Select [OK], then press < >.

8.In a moment, the reflex mirror will lock up and the shutter will open.
  • "CLn" will blink on the LCD panel.

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

10.After cleaning, 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 reflex mirror will go back down. These may result in damaging the image sensor, shutter curtains, and reflex mirror.
 - Setting the power switch to < OFF >.
 - Removing or inserting the battery.
  • 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.
