    Xerox WC7855 line

    Hi.
    WC7855 prints white line at the same place on black only as per photo.
    Cleaning itb ass did not help
    Changing whole itb ass - no change
    Replaced r1 drun - still the same line
    Swopped lph with cyan one - still the same problem on bk prints only
    I have rotated mag roller and it is evenly covered by developer.

    Do you have any other suggestions? I am thinking to swop whole developer unit from another machine but maybe someone have an advise.

      I have just removed developer assy and found that mag roller is not fully covered. I do not know how I could missed this out yesterday. I wasted time yesterday but finally problem is solved.
