Dark streaks in black only

Product Name: Xerox 700i/700 Digital Color Press
Operating System: macOS 10.14 - Mojave

Working on a Xerox 700i, there is an issue with the black in which the lines are dark as opposed to a lighter line which I see often. I replaced the drum, developer, IBT belt, and cleaned the ROS. Nothing changes and again only in the black. Any advice?IMG-3575.JPGIMG-3574.JPGIMG-3571.JPGIMG-3572.JPGIMG-3573.JPG

Hi,

The prints are the same with the old and new black drum assembly?

Have you take out the ROS and cleaned inside?

Yes the prints you see are after I replaced everything. If the ROS was dirty, wouldn't it be white streaks instead of darker streaks?

Re: Dark streaks in black only

Yes, is true, but nothing else remains in the xerographic process, possibly only the 1st BTR inside the IBT.

Anyway, I saw many ROS's very dirty.
