This is coming from the Black Drum Unit. You may be able to remove the unit and look into the slot on the top. You should see the drum which is green in color and may be able to see the lines. Not much you can do with these units so you may just have to replace it.

Replace the drum of the particlular color cartridges. To know which color you have to print in single color one by one. If problem persist then replace transfer belt .

The voids and blotches can be a bad black pcu, the voids san also be toner on the glass slat obove the pcu,s there are 4 slats one for each color, on the pcu itself on the upper side is a narrow long opening, the glass slat is above this opening when the pcu is in the printer. It will take a flashlight to see any toner on the glass.

start by cleaning the laser glass. This may well clear the issue. See if you can see toner spillage somewhere that could be preventing the laser drawing the image. Also check the fuser for a plough line .

I changed out our black photoconductor unit #165 and it solved the problem. Even though the error message did not say that the photoconductor needed changed out, it had been eight months since the last replacement. I hope this helps!

if you need any parts for that machine a have 4of them

Thank You,

If the colors are good and solid with no fades, only black streaks, then black is the culprit. I suggest replacing the black cartridge.
