Each photo taken in landscape orientation with my Olympus XZ-1 shows a dark stain on the top right, like in this example.

Does anybody else has this problem? Could it be a dump patch? How can I diagnose what's going wrong? Should I send the camera to the assistance as long as it is under guarantee? If the guarantee had expired, what would be my best options?

These kinds of questions really require an example image to get meaningful answers. – Phil Sep 10 '12 at 15:30

OK. It looks like sensor dust but seems too big. Does it always appear exactly in the same spot? It will vary in size by aperture, so try another image at F/8 and compare. If it moves, it might be in the lens (I assume the lens itself has been cleaned and that no filters are involved). – Itai Sep 10 '12 at 19:06
I tried to take a photo at F/8 and the stain is visible. If I shoot at F/1.8 the stain is quite invisible. But It's always on the same spot. – Darion Badlydone Sep 13 '12 at 6:57

I've had almost identical spot/problem with my Finepix F30 after a trip to some local waterfalls. Sent it for checkup - they said it's water damage to the sensor and cannot be easily cleaned. The price they quoted for repair was more than the current value of the F30, so I ended up buying Canon S90.

Remember, this is a small sensor camera, so dust is magnified. With the note that it is invisible at wide aperture and visible stopped down, the diagnosis is near-certain: there's a speck of dust on the low-pass filter in front of the sensor. (There's a small chance that it's a stain from water as Boby says, as well, but the sample looks more like dust to me.)

With a compact camera, sending it in for cleaning is usually the only option. This'll probably cost $100 — and they'll probably do it under warranty for you at least once. If you don't want to pay that, you can:

  • resign yourself to only shooting with wide apertures in situations where the dust isn't visible
  • clone it out in post-processing every time
  • use this as an excuse to buy an interchangeable lens camera with a dust-removal system (and where you can clean the sensor yourself if need be)

I sent it to Olympus Customer Service and I hope they are cleaning it under warranty. However I like your 3rd option! – Darion Badlydone Sep 25 '12 at 13:52
