Image Sensor Cleaning
The following interrupt image sensor cleaning: raising the built-in flash,
pressing the shutter-release, depth-of-field preview, or B button, or
using FV lock.
Cleaning is performed by vibrating the image sensor. If dust can not be
fully removed using the options in the [Clean image sensor] menu, clean
the image sensor manually (pg. 376) 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.
