    Dear Sir,
    I have DC260 Machine.
    20 days before an engineer changed my developer with new one.
    But after 1/2 days the black dots where coming on paper and dots were increasing. Still I am having this problem. (I called engineer who have changed my developer but no answer)

    I called another engineer he said "The developer is sparking & making dots on drum. DP setting is needed. There are screws have to set (tighten) on developer unit."

    What is it & how to set DP unit for not coming white dots on drum and black dots on paper.

    Pls help me. Pls show me any video how to set DP Unit

    I dont know what the DP setting is but the person who changed the developer may not have changed the ATC value. It should be a green sticker located somewhere on the developer housing. ie. 43/53/46

    Also post a pic of the image fault.

    Toner clumps... Either you are using non Xerox toner or the stuff you are using has been subjected to extreme heat.
