I was able to fix it by taking off the top of the printer. This involved taking off 4 screws on the top of the printer. I then had to disconnect the wires going to the control panel by unhooking them from the right side. I then located a thin rectangular box which I'm assuming houses the laser. I removed this with 4 more screws and turned it over. There was a little metal flap that I moved back and below was the mirror the lasers shoot on before going onto the toner.
In the same spot where I was having fading, I noticed a lot of toner on the mirror, so I cleaned it of, put it back together, and the fading was gone.
This was after I tried a new toner and maintenance kit.
Hope this helps

Your scanner lamp is dirty. Take apart the scanner glass and clean the lamp. (Look for contaminated spots on the scanner lamp).
