    Memories...

    Any one remember the old SF 7900.
    Just wondered if any one recalled what the DV bias voltage would normaly measure.
    I have one that is reading between -200 and 202 VDC and I am thinking that is low.
    Yes I know its a old machine, but this is one of them times I have to bite my tounge and not say what I want to about the old POS.
    DV, drum and blade were changed a while back, and I am thinking them suppies were old to start with.
    Not even sure where they found them at

    Test command 8 should read -200vdc for DV bias.

      That level sounds okay to me for an old Sharp analog. Are your copies too dark? How is the foam roller in the bottom of the toner hopper?
