I have a void when I run a copy thru cyan, its a line that looks like it's a drag,I replaced the drum in the unit and cleaned the fuser, Any Ideas in what it can be.

Clean laser shield glass, or look at dev roller.

It is most likely a chunk of hardened developer. Either replace the DV unit, or thoroughly clean it out and put in fresh developer.

Re: mpc4502

Have another really good look, it has to be laser or lump in dev unit.

Bottom section of the sky shot image looks similar to a charge roller shorting out in the PCU.
With regards to the linear lines, I'm leaning toward dev lumps causing voids.

+1 on Dev. Unit or Shield glass. The bottom part that's faded could just be from overhead lights during skyshot.

Re: mpc4502

I've seen brand new PCU's with dev voids straight from the supplier warehouse.
Probably the last of that years old PCU stocks sitting around the in warehouse.
