    VD= Voltage in Dark Area

    Many things effect Drum life,
    most important is Printer Environment location ,Static Electricity & % Coverage of printing-

    Wherever a photon of light hits, electrons are emitted from the photo-conductive atoms in the drum and neutralize the positive charges above.
    Dark areas on the original (such as pictures or text) do not reflect light onto the drum, leaving regions of positive charges on the drum's surface.
    **Knowledge is time consuming, exhausting and costly for a trained Tech.**
