Image Sensor Cleaning
If you suspect that dirt or dust on the image sensor is appearing
in photographs, the sensor can be cleaned manually as
described below. Note, however, that the sensor is extremely
delicate and easily damaged. Nikon recommends that the
sensor be cleaned only by Nikon-authorized service personnel.

A reliable power source is required when inspecting or
cleaning the image sensor. Turn the camera off and insert a
fully-charged battery or connect an optional AC adapter and
power connector. The Lock mirror up for cleaning option is
only available in the setup menu if the camera is not
connected to a smart device via Bluetooth and the battery
level is over H.
