    After changing the consumables, did you follow the steps from service manual?

    Check the second transfer roll or make adjustments to compensate for the second transfer. With software SW 1-0 ON, this setting appears in the paper setting on the main panel of the machine.

    Then, adjust (adjust operation run) with four options. After, make calibration via Spectrofotometer I1

    Re: Gradation in 6501

    Thanx Mac,
    Ill try and come back,whether the gamma offset adjustment can create any other problem?
    why the colorbands are appearing while printing the gray in color mode.If print from gray scale mode the colorbands are not appearing,but the gradation is not smooth.Is this the limitation of IC408 compare to Ic305.Which color set up will be better for the files with gray and color?Any problem in printing from PDF compare to coreldraw or photoshop?

    Sorry lot of questions.Can help me please!!!!!
