    Wc 7830 image problem

    17338391340173016176812677900513.jpg
    Hello guys

    I have a strange problem, on every full color print i have many white "dots"... If i use the "repeated defects sheet" nothing matches the distance of my defect, that is 25mm from dot to dot. I've already changed all 4 Pcu's from a working machine but nothing changes. The transfer belt seems good, the fusing unit is perfect.... Any ideas?
    Thank you!
