Automatic Sensor Cleaning; Clean Now - Canon EOS 1D Instruction Manual

Automatic Sensor Cleaning

3
Whenever you set the power switch to <1/J> or <2>, the Self Cleaning
Sensor Unit operates (approx. 3.5 sec.) to automatically shake off any dust on
the front of the sensor. Normally, you need not be aware of this operation.
However, you can execute the sensor cleaning at anytime as well as disable it.
Cleaning the Sensor Now
The user-executed cleaning takes about 4 sec. to complete. During the
sensor cleaning, the shutter will make 3 shutter-release sounds.
However, the image will not actually be taken.
For best results, do the sensor cleaning while the camera bottom is
placed on a table or other surface at a perpendicular angle.
Even if you repeat the sensor cleaning multiple times, the result will not
improve that much. Right after the sensor cleaning is finished, the
[Cleaning nowf] option will remain disabled temporarily.
Disabling Automatic Sensor Cleaning
In step 2, select [Auto cleaningf] and set it to [Disable].
Whenever you set the power switch to <1/J> or <2>, the
sensor cleaning will not be executed.
