    [CQ] H.P. 2840 all in one color CQ and PQ problem?

    On b/w printed or copied docs, there is a one inch white vertical band one inch from left margine.
    Color copies or prints, everything looks great, except the black.
    A solid red font doc prints and copies great.
    I cleaned and vacuumed the monster, tried another black toner cart

    PLEASE HELP... Thanks
