    Hi,

    I just received a new Bizhub C284e.
    Printouts show regular patterned spots. Step is about 13mm.
    The pattern is the same for every color.
    When printing 100% color coverage I get the worst results (see the BW image).
    When printing 10% color coverage, the pattern is hardly visible.
    Tried all the options in "Service Mode". Did not help.
    Any ideas what could be the problem?

    Thanks in advance!

    It looks like your developer units are failing. Do you have toner in the machine ? and if so is it genuine toner ?
