      Most likely you are not using an OEM drum unit! These models of machines have unique drum units; technical specifications refer to it as an E-DRUM, I haven't bothered though to find out what the letter 'E' stands for. But I have a machine with a drum count now 375,000 copies and still running clear copies, even though the stipulated drum lifespan is 169,000 copies; You must have noticed that the drum cleaning blade has very thick blade too.

      In your case, assuming your using after market drum unit, the drum cylinder could be slightly shorter and the bias contact plate in the cylinder is NOT making proper contact with that in the machine body, hence the dark prints.
      You may try to 'elongate' the cylinder by inserting REASONABLY thick plastic washer, or piece of thick paper in between the front end of the cylinder and its cleaner assembly before inserting the drum lock pin. This will 'elongate the drum cylinder 'long' enough to reach the contact at machine's rear. Good Luck.

              once happened with me when i tried to clean the machine from the dust ,i removed the laser to cleaned it then i turned it back without turned back the covers the machine on copy gave me full black copy as u showed us , i assembled back the covers and the machine it works normally i wonder in this model about this if you removed the covers that located above the hooper the problem occur so make sure that the all the covers are set .
