Ws6000 Banding problem!!!

Dear all
I attach picture of problem that I’m trying to fix on press of my customer.
Banding is fixed, in all colors, any suggestion?

 

Hey Guys!!! No idea on this problem?

 

The strange is that the first line is aprox at 44/46 the second at 130/132 and this going to repeat continuously...
45/85/45/85/45/85/45/85....
45+85=130
from 45 to 45 is 130
from 85 to 85 is 130
I can't fine and defect on the tenth of Pip and Blanket Drum... also the main motor... and I put all colors New Bid...

The only Idea now is the Charge Roller... this issue seems to be from wrong charge...
But believe me I can't find the problem....

Pls... if anyone have an idea I'm here to listen...
