DImage Sensor Cleaning

Using camera controls interrupts image sensor cleaning. Image sensor cleaning may not be performed at startup if the flash is charging.

Cleaning is performed by vibrating the low-pass filter. If dust can not be fully removed using the options in the Clean image sensor menu, clean the image sensor manually (0 182) or consult a Nikon-authorized service representative.

If image sensor cleaning is performed several times in succession, image sensor cleaning may be temporarily disabled to protect the camera’s internal circuitry. Cleaning can be performed again after a short wait.
