How to clean image sensor? - Nikon D80 Digital Camera

Because that model does not have them, it is all electronic the sensor are in the image units

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

The image sensor in the Coolpix S200 is not self cleaning. There are a number of videos on YouTube that say they show you how to clean it, but unless your camera is really effected by a dirty sensor and you are very skilled at disassembling tiny electronic devices, I wouldn't recommend them.

Black, unremovable dots are probably bad pixels in the sensor. These are parts of the sensor that no longer react to light. If you don't see any issue looking through the viewfinder, then the sensor is messed up. Since you say you don't see anything on the surface, I assume the optical part of the camera is in tact. You can try cleaning the sensor - Menu - Setup - Clean Image Sensor - it certainly can't hurt.

This is probably due to dust or other foreign matter on the CCD. Look at the Pentax *ist DL manual under "CCD cleaning" or "sensor cleaning" for instructions.

There is a "sensor cleaning" mode in the Set-up menu that will lock the mirror up so you can inspect/clean the CCD sensor.

Sorry, I read this as being for a Nikon N70 35mm SLR, but now see that it's a Canon EOS 350d.

In that case, you simply have a dirty image sensor. Either use a DIY sensor cleaning kit on the sensor (put the camera body into "sensor cleaning mode" to expose the sensor), or get a professional cleaning done. Professional is best for a one off, but as the problem will re-occur then there's no substitute for the experience you'll gain by doing it yourself. Until you get good at sensor cleaning, just clone out the artefacts using your preferred image editing software.

Does the camer have a removable lens. Is it an SLR camera. If so, there probably is microscopic dust on your sensor, or you have some dead pixels on your sensor. If you can get to the sensor, you can easily clean it with a cleaning kit. The most effective way of cleaning is to blow it off with clean air. Be gentle. On an SLR it is necessary to lock the mirror up. Your instruction book will explain how to do that. For more suggestions, Google cleaning my camera sensor and you will get a lot of suggestions. :-)
