    White dots on solid prints.

    Hi
    I am having white dots on solid prints (could be on text also but can't verify).
    Machine is a IR8105 and developer unit is new one, transfer belt(film) is also new.
    Could be drum? Drum heater is on.
    Any idea?
    Thank you

    you said 'film' is new... did you clean the rollers below the belt/film? they can build up crap on them and cause spots..
    could also be the drum or even paper.

    and pics of the problem?

      Did you rewire the coronas?

                I hate coronas. Especially when I lose spring on a gray carpet.

                  yup ..sucks worse than a 2bit ho!

                  I used curved hemostats to hold spring while stringing that end.

                    Hemostat!? Good idea!

                    And for other side? Hex key?
