Cleaning dust off sensors

Cleaning the sensor properly is a job for a professional service centre. You can render the warranty of a camera void by attempting to clean the sensor yourself. It is also very easy to damage a sensor by touching it and they are extremely expensive to replace.

However, in circumstances where there is dust on the sensor and the automated cleaning process is not working and there is no alternative, you can try the following:

Switch the camera to manual sensor cleaning, which will lock up the mirror and open the shutter. Remove the lens, which will allow you to see the sensor, and then hold the camera facing downwards so that the dust particles can fall out of the body. Give several puffs of air to the sensor from a blower. Keep the tip of the blower just inside the camera and well away from the sensor. Under no circumstances touch the sensor. Do NOT use compressed air. Replace the lens, turn the camera off and then on again and take test shots to see if the dust has cleared.

To check for dust on the sensor: choose Aperture Priority (A on a Nikon, Av on a Canon) and set the lens to f16. Fill the frame with a clean white sheet of paper or a similar single pale tone, focus and shoot. Examine the file on a computer screen. Repeat if necessary.
