      From what I can see on the sheet it looks like a dirty grid or charge wire and possibly a worn out drum which gives the same effect. Swop these parts and fault should clear. What is the drum count?
      Please do not PM me without asking first.

          I totally agree with minimerlin, charge grid and if the drum is close to life, change it also.
