Black Spec on Photo

I'm getting a black spec on my photo's. When I zoom in it looks to be one black pixel. This does not show on the dust check, the sensor looks to be perfect. Have tried a different lens and still the same. Can anyone advise please?

The black pixel? Is just below the lis on the right side

I couldn't find it, but if it's a single dot and doesn't change appearance based on aperture, then it's probably a dead pixel. Try using pixel mapping to nap it out.

Under the lip/mouth on the right? I can just barely see it. If it follows through with different lenses and doesn't show up in dust detection, yeah its probably a bad pixel.

I can't see it either but this demonstrates how useful the dust detection system really is. Point your camera at a white (or similar) surface and walk through the apertures taking photos. As adam says, if it's there at All the apertures, run your pixel mapping (setup menu). Run it anyway. If it gets more visible as you stop the lens down toward f22, it's dust.
