Image Sensor Cleaning

If you suspect that dirt or dust on the image sensor is appearing
in photographs, you can clean the sensor using the Clean image
sensor option in the setup menu. The sensor can be cleaned at
any time using the Clean now option, or cleaning can be
performed automatically when the camera is turned on or off.
❚❚ "Clean Now"
Holding the camera base down, select
Clean image sensor in the setup menu,
then highlight Clean now and press J.
The camera will check the image sensor
and then begin cleaning. 1 flashes in
the viewfinder and other operations can
not be performed while cleaning is in
progress. Do not remove or disconnect
the power source until cleaning ends and
the setup menu is displayed.
