Soap film on Canon 5000f
I just bought the Canon 5000f scanner a couple of days ago. The glass on it is perfectly clean, but when the light is on inside of it you can see a film of soap on the bottom side of the glass. You can tell because it is absent in some parts of it. There was also a heavy film of soap on the top of the glass but I cleaned it off. Like I said, the glass looks perfectly clean, it is only when the scanning light is on when I can see it. I am new to scanning so I don't know what I should do about it. Will this film have any effect on the images I scan? I wouldn't be able to tell because I wouldn't have any other scanned images to compare it to. I bought it off the internet so I can't really take it back. If I exhanged it Canon would give me a refurbished one, which is not what I want. Is it worth it to take it to a repair shop to have it clean or should I leave well enough alone?
