    Automatic Sensor Cleaning

    • Answer
    • In the following cameras, whenever you turn the power switch to on or off, the Self Cleaning Sensor Unit is activated to automatically shake off the dust on the front of the sensor (CMOS).

      • EOS-1Ds Mark III
      • EOS-1D Mark IV
      • EOS-1D Mark III
      • EOS 5D Mark II
      • EOS 7D
      • EOS 60D
      • EOS 50D
      • EOS 40D
      • EOS REBEL T3i/EOS 600D
      • EOS REBEL T2i/EOS 550D
      • EOS REBEL T1i/EOS 500D
      • EOS REBEL XS/EOS 1000D

      Normally, you need not pay attention to this operation. However, you can run the sensor cleaning at any time by following the procedures below.


      This section explains the procedures using the EOS REBEL T3i/EOS 600D. Depending on the model you are using, the content displayed on the LCD monitor might be slightly different from what is shown on your camera, but the procedure is almost the same.

      1. Set the power switch to .

      2. Press the

      button to bring up the menu display.

      3. Under the [Set-up] tab, select [Sensor cleaning], then press the button. 

      The [Set-up] tab to be selected is different depending on the model. For details, please see the list below.

      4. The screen below will appear. Select [Clean now], then press the button. For EOS DIGITAL REBEL XTi/EOS 400D DIGITAL, go to step 5.

      5. Select [OK], then press the button.
      The screen will indicate that the sensor is being cleaned. Although there will be a shutter sound, a picture is not taken.
      For EOS DIGITAL REBEL XTi/EOS 400D DIGITAL, select [Clean now] then press the button.


      • For best results, do the sensor cleaning while the camera bottom is placed on a table or other flat surface.
      • Even if you repeat the sensor cleaning, the result will not improve that much. Right after the sensor cleaning is finished, the [Clean now] option will remain disabled temporarily.

      If there is dirt or dust that cannot be removed by following the procedure above, please see Manual Sensor Cleaning.


      • Normally, the Self Cleaning Sensor Unit will eliminate most of the dust that might be visible on captured images. However, in case visible dust still remains, you can append the Dust Delete Data to the image for erasing the dust spots later. The Dust Delete Data is used by Digital Photo Professional (provided software) to erase the dust spots automatically.
      • For details about dust delete data, refer to the instruction manuals that came with your camera. For Automatic Dust Erasure Processing using Dust Delete Data, please see How to erase dust spots in an image with Digital Photo Professional Ver.3.10 (Copy Stamp Tool).
