For best results, perform the sensor cleaning with the camera placed 
upright and stable on a table or other flat surface.
 Even if you repeat the sensor cleaning, the result will not improve much. 
Immediately after the sensor  cleaning is finished, the [Clean nowf] 
option remains disabled temporarily.

Normally, the Self Cleaning Sensor Unit will eliminate most of the dust 
that may 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 (EOS software , p.404) to erase the dust spots 
automatically.
Prepare a solid white object such as a sheet of paper.
 Set the lens focal length to 50 mm or longer.
 Set the lens focus mode switch to < MF> and set the focus to infinity 
( u ). If the lens has no distance scale, rotate the camera to face 
towards you and turn the focusing ring clockwise all the way.
1Select [Dust Delete Data].
 Under the [z 3] tab, select [Dust 
Delete Data ], then press < 0>.
2Select [OK].
 Select [ OK] and press < 0>. After 
the automatic self-cleaning of the 
sensor is performed, a message will 
appear. Although there will be a 
shutter sound during the cleaning, no 
picture is taken.

3 Appending Dust Delete Data K
3Shoot a solid-white object.
At a distance of 20 cm - 30 cm (0.7 ft. 
- 1.0 ft.), fill the viewfinder with a 
patternless, solid-white object and 
take a picture.

The picture will be taken in aperture-
priority AE mode at an aperture of f/22.
 Since the image will not be saved, the 
data can still be obtained even if there 
is no card in the camera.

When the picture is taken, the camera 
will start collecting the Dust Delete 
Data. When the Dust Delete Data is 
obtained, a message will appear.
Select [
OK] and the menu will 
reappear.
If the data is not obtained successfully, 
an error message will appear. Follow 
the “Preparation” procedure on the 
preceding page, then select [
OK]. Take 
the picture again.
After the Dust Delete Data is obtained, it is appended to all the JPEG 
and RAW images captured thereafter. Before an important shoot, it is 
recommended to update the Dust Delete Data by obtaining it again.
For details about using Digital Photo Professional (EOS software) to 
erase dust spots, refer to the Digital Photo Professional Instruction 
Manual (p.406).
The Dust Delete Data appended to the image is so small that it hardly 
affects the image file size.
Dust Delete Data
Be sure to use a solid-white object such as a new sheet of white paper. If the 
object has any pattern or design, it  may be recognized as dust data and 
affect the accuracy of the dust deletion with EOS software.

Dust that could not be removed by the automatic sensor cleaning can 
be removed manually with a commercially-available blower, etc. Before 
cleaning the sensor, detach the lens from the camera.
The image sensor is extremely delicate. If the sensor needs to be 
cleaned directly, having it done by a Canon Service Center is 
recommended.
1Select [Sensor cleaning].
 Under the [5 3] tab, select [ Sensor 
cleaning ], then press < 0>.
2Select [Clean manually].
 Select [ Clean manually ], then press 
< 0 >.
3Select [OK].
 Select [ OK], then press < 0>.
 In a moment, the reflex mirror will 
lockup and the shutter will open.
4Clean the sensor.
5End the cleaning.
 Set the power switch to < 2>.

If you use a battery, make sure it is fully charged.
For the power source, using AC Adapter Kit ACK-E18 (sold separately) is 
recommended.

3 Manual Sensor Cleaning K
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 < 2>.
•  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. The blowing force 
can damage the sensor, or the spray gas can 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.
