I don't believe recent Nikon cameras let you do this yourself. If the
camera is under warranty send it in Nikon will go over the whole
camera. I'd advise you to send the camera in.
Hot pixels should be red or blue, dirt should be black. Nikon has been
using an anti static coating on their AA filter, which is where the
dust is, not directly on the sensor. On the D200 there isn't much of a
dust problem, I change lenses a lot and in a year I have blown off my
sensor twice. From Nikon groups my experience seems common. I would
assume they are using this on all their DSLRs.

Once, I had several pinpoint black spots appearing on all the photos taken
with a SLR camera.

The spots could be viewed on a monitor or in a print. Cleaning the lens did
not erase the spots. So, to clean the sensor, I followed the steps below.

(1) Tried another lens to see if the dirt was on the lens or sensor. The
spots were on the sensor, not the lens.

(2) Removed the lens, and turned the camera body upside down so the camera
opening was facing down.

(3) Used a camera blow brush to remove the dirt from the sensor.

This process worked like a charm. I'm tempted to do this process on all my
digital SLR cameras, but have not done so. Will wait until the sensors are
dirty, since I am now more careful when changing lens. I learned this
cleaning process from a camera shop employee.

Are there other ways to clean a sensor?

It is really for dirt on the sensor that cannot be removed. It is only a
temporary fix. The sensor should be cleaned.
