a dark hairy like mark! HELP! HELP

On the top right, there is a dark birdy-like mark, but it appears on every picture i took. Is this a dust on sensor? but dust alert shows nothing. dust removal can do nothing about it. What can I do? Help me please! I only brought this 9 days ago.

It only can be seen when view the taken picture in the playback or on the computer, but not from the viewfinder.

Asking this without posting a sample picture is a bit like calling your optometrist and asking him to do an eye exam over the phone.
I'm sure if you post a sample or two you will get the answer.

I only bought it 9 days ago & used it for 4 days, and this is my first SLR. How often do we have to clean the sensor?

To answer your most recent question, whenever necessary. There is no fixed amount of time interval for doing so.

You should be able to remove that kind of spot with an air blower. Just try the blower on another surface first, because some of them throw talc, and that's much harder to remove (don't ask how I know).

Perhaps I'm paranoid but I always ensure that the sensor is pointing down whilst I change a lens, and I always have the other lens in hand ready to go on, I figure a speck of dust on the lens is easier to fix than on the sensor.

Dust cannot get on the sensor until the shutter opens. While it's a good idea to point the camera downward to prevent anything from falling in, it would also be wise to keep the rear of the lens and the lens mount around the camera clean. Either way, it isn't the end of the world. Some have been disappointed to see this on a factory brand new out of the box first shot camera. Even if a lens is kept on the camera, most suck air (and dust) in and push it out as they are focusing. So the best course of action is just to learn how to deal with it.

here in Texas, I get dust on my Kx, I use the dust removal and use a Giottos blower. I have a soft brush and use the blower on my lenses before and after I use them. It has helped a lot.

I've found that turning off the camera when changing lenses really helps keep the need for sensor cleaning down, as it reduces the static electricity in the sensor I guess.
