Before you begin
First try the automatic sensor cleaning fuction on your camera, but if that does not remove all the dirt or dust on the image sensor (CMOS), or if your camera does not have that function, you can manually clean the sensor following the steps in this article using a commercially available blower.
Important - The surface of the image sensor is
extremely delicate. Clean the sensor with care. If the sensor needs to be cleaned directly, we recommend that you
contact a Canon Service Center.
Keep power on during cleaning
- We recommend using an AC Adapter Kit ACK- E6 (sold separately) during the cleaning process.
- If you use a battery, make sure it is fully charged. If the Battery Grip BG-E16 (sold separately) with size-AA/LR6 batteries is attached, manual sensor cleaning will not be possible.
Steps for manual sensor cleaning
Good to know
To avoid damaging the shutter curtains and the image sensor during cleaning:
- Do not set the power switch to OFF.
- Do not open the battery compartment cover.
- Do not open the card slot cover.
- Do not insert the blower tip inside the camera beyond the lens mount.
Additional precautions
- If the battery level becomes low while you clean the sensor, the beeper will sound as a warning. Stop cleaning the sensor.
- If a smudge that cannot be removed with a blower remains, we recommend getting the sensor cleaned by a Canon Service Center.
