    I can see the shaded lines repeating pattern..Seems K drum....Set Background voltage of K to 3 if already 0 (default), this should single out K drum.

    Also your samples were these printed SEF or LEF ?

    However the print defect looks black & your black drum has 3% remaining I would suspect that is the issue.


    I will run the gradation test prints by tomorrow if the problem still persists.

    A4 - LEF / A3 - SEF

    Yea, Will replace the drum tomorrow.

    I don't really want to mess with the voltages, but after replacing the drum I shall give it try is it's not fixed.

    Oh it's not messing up...it's there in setup and presumably for the same purpose... we usually do this to check same type of drum problems..... I would not change these settings after new drum......
