Cleaning Instructions for the Fuji S3 and Nikon D200
Checking for dust.
If one of our cameras gets large dust specks on the sensor, the marks will be
clearly visible in its images. Often sensors get infested with less prominent dust
spots – these will not be so visible but will cause a lot of fiddly work for people
photo-shopping images ready for printing.
To see how much dust is on a sensor, take a picture of an even, bright thing
(the sky usually) with the camera stopped down to about f22. Look at the
image on a laptop. If there are a few lightish spots there will be no need for
action but if there are any big/dark spots or lots and lots of light to medium
spots, the camera will need cleaning.
The sensors in these cameras are, of course, delicate and important to the
proper working of the camera. Fuji and Nikon are very clear in taking no
responsibility for users damaging the chips while cleaning them and it would
be an expensive mistake to ruin them.
The two things to pay particular attention to are:
1. Make sure you don’t scratch the sensor. Only touch a sensor with an
appropriate swab (supplied in the cleaning kit) and NEVER blow air
directly at the sensor (only use the air provided in the cleaning kit in the
2. To get to the sensor you need to raise the shutter of the camera. Make
sure you have fresh batteries in the camera each time you clean it so
there is minimal risk the shutter will come back down while you have
The kit provided has instructions for how to use the air as a mini vacuum
cleaner. Please follow these carefully. It also contains swabs to wipe across
the sensor after you have vacuumed it. Please use the wet swabs and not
the dry ones.
Here’s how you gain access to the sensors in the Fuji and Nikon D200:
1. Start with the camera turned off and the lens taken off the front of the
2. Simultaneously hold down the little flash button (below the wheel on
the top left of the camera) and the little light bulb button (next to the
top LCD display) and at the same time turn the camera on.
3. If you have managed step 2 correctly, the top LCD display will show ‘- -
F - -‘. At this point press the shutter release button and the shutter will
be raised leaving the sensor visible.
4. Clean the sensor as per the instructions in the kit.
5. Turn the camera off and the shutter will come back down.
6. Put the lens back on.
7. Take a test shot and look for dust. Repeat the whole process if
1. The D200 has a menu item called ‘Mirror up’. It is one option in the
submenu with a spanner icon. When you select it and subsequently
press the shutter release, the mirror locks up to reveal the sensor.
2. Clean the sensor as per the instructions in the kit.
3. Put the mirror down again, put the lens back and take a test shot.
4. Repeat the cleaning process if the test shot shows you need to.
