    if i understand right u r getting dark on the bottom or top of pages which usually is the charge roller dirty, clean with soft cloth and very little water and allow to dry completely. i'm sure you checked optics and laser slits clean?

      black and white copies are good, the printing of the test color is good, making a color copy there is a uniform background of all the press seems to have adjusted to the maximum dark

        Are you getting print right? does it only happen with copies?if so then make sure you got the mirrors,ARDF mayler,and scanning glass clean. if it doesn't help you out try to lift the scanner from left front.it normally gets bent with a push and create some weird problems like background or lines in copies! good luck!

          to explain, printing and copying is good, this fund is clear, it seems a problem of automatic exposure, adjusting manually to clear up the bottom disappears

            There's some sort of adjustment in SP4xxx for coloured backgrounding but I can't remember what it is. Get the birth certificate out and check your settings.Out of interest, have you replaced the NVRAM recently?

                Replacing the NVRAM can cause some odd backgrounding faults. Anyway, back to SP4xxx for you...

                    Llama God is on the right track. The grayscale setting has reset to default value. Not sure of the exact sp, just check the factory data sheet against what is currently programmed.
