Automatic Sensor Cleaning - Canon EOS 250D Advanced User's Manual

Automatic Sensor Cleaning

Whenever you set the power switch to <1> or <2>, the Self Cleaning
Sensor Unit is activated to automatically shake off the dust on the front of
the sensor. Normally, you need not pay attention to this operation. However,
you can manually perform sensor cleaning or can disable this unit as follows.
Activating the Sensor Cleaning Manually
When Multi Shot Noise Reduction is set, [Clean nowf] cannot be selected.
z
For best results, perform the sensor cleaning with the camera placed upright
z
and stable on a table or other flat surface.
Even if you repeat the sensor cleaning, the result will not improve much.
z
Immediately after the sensor cleaning is finished, the [Clean nowf] option
remains disabled temporarily.
Dots of light may appear on the shooting screen if the sensor is affected
z
by cosmic rays or similar factors. By selecting [Clean nowf], their
appearance may be suppressed (= 475).
Disabling Automatic Sensor Cleaning
In step 2, select [Auto cleaningf] and set it to [Disable].

The sensor will no longer be cleaned when you set the power switch
B
to <1> or <2>.

The screen will indicate that the sensor

is being cleaned. (A small sound may

mechanical sound of the shutter during
the cleaning, no picture is taken.
