Automatic Sensor Cleaning - Canon EOS 77D Instruction Manual

f Automatic Sensor Cleaning
Whenever you set the power switch to <1> or <2>, the Self
Cleaning Sensor Unit is activated to automatically shake off any 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.
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.
Dots of light may appear on images if the sensor is affected by cosmic

rays, etc. By selecting [Clean nowf], their appearance may be
suppressed (p.466).
