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 control panel 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.
