Bizhub 601White Marks on halftone

[SmellsHot]

Hey everyone!
I'm having an issue with this 601. I'm getting little white void marks on internal halftones(shows up on everything else as well)
I've attached a sample of what it's doing. It's a weird one. Machine wasn't/isn't misting/dumping currently. I've replaced Drum,Dev, Pm kit parts. Ran all proper adjustments.
It's weird as it seems to do it mostly towards the edges of the prints. The t&s and charge look visibly fine. Has anyone seen this before.
TIA

What does the fuser look like?

Sorry. Forgot to mention its pre fuser and the fuser is like new!
Thanks for the quick response though

I would change the charge grid and wire. Also change the transfer wire. Might as well make it all new.

The more suggestions u guys give the more i realize i left out of what i did...haha
Thanks for the prompt responses. I ended up figuring it out. It looks like the customer pulled up on the middle of the metal t&s guid and bent it. Hard to notice when u dont have another to compare too. I ended up swapping out the whole t&s unit and my problem went away!
Thanks again guys

Thanks for letting us know the fix.

I wish they would change the lock paint on those 3 screws used to set the height of the guide on the T/S. They have been coming loose since the 7155s.
