Re: C6500 with blue background

C-2804 is an issue with the black channel.
Inspect your dev sleeve to see that sufficient developer is adhering to the sleeve.
Thoroughly clean you color registration unit (Gamma sensor)
Ensure your charge unit is installed correctly.
Ensure your transfer belt is not too far to one side and causing it to buckle.
Try printing test pattern 81 and see if your black on that page is acceptable.
Run Auto Gamma once you have diagnosed the issue with black. This should clear up your "blue" background.
Hope this helps.
