Inside the camera is a mirror which reflects the scene up to the viewfinder. It flips out of the way when you press the shutter button. When the mirror flips up, the shutter opens and exposes the sensor. When you look inside, if the mirror is stuck in an up position, you will not see anything in the viewfinder. However, the mirror is super delicate....do not touch its surface or try to force it.

This is almost certainly due to dirt on your lens or mirror - possibly your sensor. If you have two interchangable lenses try them both and see if there is a difference. If no difference the mirror or sensor is probably dirty. In either case, I would suggest you have them cleaned professionally unless you are confident about working inside your camera. If there is no smudge with one lens then the other lens must be dirty. Clean both ends carefully with soft, lint free cloth.

i have the same problem but mine has a blue line surrounding the screen the tech took out the fly wheel part from inside this part has the 3 main colors with strips the blue side strip if you look at the glass it has the problem you see on your screen you have to replace that one section

Are you talking about spots you see on the pictures? Are these spots you see in the same place on all the pictures? If you really want to see if your sensor is dirty pick a clear day with a great blue sky focus to infinity and then shift the lens to manual focus and the program to "P" take a pitch of the blue sky. Then down load this picture to the computer and open it up to 100% and look it over if there are spots then the sensor should be cleaned. Even if you take the lens off and look into the camera body you still can't see the sensor all you are looking at is the mirror inside the prism box.
To clean the sensor you need to put the camera into "clean" mode which locks the mirror up. It may be possible you just have a dirty lens or UV filter.

If you switch lenses and the hair is still appearing on your pictures, it is quite possible you have an actual hair or thread or something located in the camera body in the way of the sensor. Remove your lens and visually examine the inside of the body for debris. Stay clear of the sensor and the mirror, but you can use tweezers to remove an obvious foreign object. You can also command your mirror to stay up and out of the way (see the camera setup menu "mirror lock up") for closer examination. It's best to use a bulb type squeeze blower to blow out debris from inside the camera. Do an internet search on "rocket air blower" and you'll see what I mean. Blowing air from your mouth can introduce moisture.

Try to dust off the inside of the body, the mirror and ckeck if it is movin gorectly or if there's something in the way. Also it mai be "something scratching the negative from the front or the back, check your negative."

You need to clean the mirrors inside your projector, you can either open the shell and use compressed air, but i will recomende u to go to someone who works with things like that. Its cheap to clean a projector by a pro, it takes a pro about 10-15 minits to do it.

If u gona use compressed air, make sure u biy air special for elecronics and nevere ever hold it near the mirrors.

Good luck!

If you're still getting smudges, there must still be a label or part of a label either on one of the image drums or the transfer belt, i've found in the past it somethings gets stuck inside the unit on the cleaning blade. What i suggest is you run a print and open the front door at the paper travels along the transfer belt, look at all the image drums and see if you can see the smudge on one of them, if so the problem is caused by that cartridge if not it's in the transfer belt somewhere. You may need to try stopping the printer a few times and if the problem is in one of the cartridges, you will mst likely have to replace it, as with the transfer belt if you think that's causing the problem it's easier to remove it and rotate the belt manually.

Please note the image drums and the transfer belt are all light sensative
