❚❚Manual Cleaning

If foreign matter can not be removed from the low-pass filter using the Clean image
sensor
option in the setup menu (

0 210), the filter can be cleaned manually as

described below. Note, however, that the filter is extremely delicate and easily
damaged. Nikon recommends that the filter be cleaned only by Nikon-authorized
service personnel.

1

Charge the battery or connect an AC adapter.

A reliable power source is required when inspecting or cleaning the low-pass
filter. Turn the camera off and insert a fully-charged EN-EL14 battery or connect
an optional EP-5A power connector and EH-5b AC adapter.

2

Remove the lens.

Turn the camera off and remove the lens.

3

Select Lock mirror up for cleaning.

Turn the camera on and press the

G

button to display the menus. Highlight Lock
mirror up for cleaning
in the setup menu
and press

2 (note that this option is not

available at battery levels of

H or below).

4

Press

J.

The message shown at right will be displayed in the
monitor. To restore normal operation without inspecting
the low-pass filter, turn the camera off.

5

Raise the mirror.

Press the shutter-release button all the way down. The
mirror will be raised and the shutter curtain will open,
revealing the low-pass filter.

6

Examine the low-pass filter.

Holding the camera so that light falls on the low-pass filter,
examine the filter for dust or lint. If no foreign objects are
present, proceed to Step 8.
