Samsung Color laster printer ghost printing??

I noticed lately my LX-3175FN/XAA is now making faded prints on the same page as though it wasn't feeding the paper fast enough or the image seems double with the second half way down the page but faded look. I looked online for various reason and found one stating that the imaging drum need to be replaced and another said the fuser. So has anyone had this problem and found a way to fix it? I am considering getting a new imaging drum as it isn't expensive because the printer still work and does it's other function fine. It is just the printout that concerns me if this is a hardware problem I can fix or does this mean the money I just recently spent on the toners for a printer on it's way out. I had this for 5 years before this recent problem started happening.
