244 Technical Notes
7 Clean the sensor.
Remove any dust and lint from the sensor with a blower.
Do not use a blower-brush, as the bristles could damage
the sensor.
Dirt that can not be removed with a blower can
only be removed by Nikon-authorized service personnel.
Under no circumstances should you touch or wipe the
sensor.
8 Turn the camera off.
The mirror will return to the down position and the shutter curtain will close.
Replace the lens or body cap.
A Use a Reliable Power Source
The shutter curtain is delicate and easily damaged. If the camera powers off while the mirror
is raised, the curtain will close automatically. To prevent damage to the curtain, observe the
following precautions:
• Do not turn the camera off or remove or disconnect the power source while the mirror is
raised.
• If the battery runs low while the mirror is raised, a beep will sound and the self-timer lamp
will flash to warn that the shutter curtain will close and the mirror will be lowered after
about two minutes.
End cleaning or inspection immediately.
D Foreign Matter on the Image Sensor
Foreign matter entering the camera when lenses or body caps are removed or exchanged (or
in rare circumstances lubricant or fine particles from the camera itself) may adhere to the
image sensor, where it may appear in photographs taken under certain conditions. To
protect the camera when no lens is in place, be sure to replace the body cap provided with
the camera, being careful to first remove all dust and other foreign matter that may be
adhering to the camera mount, lens mount, and body cap. Avoid attaching the body cap or
exchanging lenses in dusty environments.
Should foreign matter find its way onto the image sensor, use the image sensor cleaning
option as described on page 241. If the problem persists, clean the sensor manually (0 243)
or have the sensor cleaned by authorized Nikon service personnel. Photographs affected by
the presence of foreign matter on the sensor can be retouched using the clean image
options available in some imaging applications.
