    ricoh c6000 black lines

    having black lines on color and black and white when paper thickness set to normal paper, but when paper thickness is set to thick one (no lines). lines are running from lead to trail edge. they are multi lines and are faded grey lines coming and going. looks to me like the black charge corona on the black drum unit is causing the problem. just installed new ts belt and blades. problem was there before.
    customer neglected this copier so i am replacing parts as they can afford. previous parts changed in near past was all drums and related parts in the image unit then all developers.
    puzzled it does it on normal paper thickness but not on thick one. cover page and card stock looks great.
    also my black density is light and color density is good for y,m and c. super cleaned copier and ts unit yesterday. developer is not that old. thanks

      Pictures, please.
      In the mean time, best guess: bad non-OEM toner.

          Take a good hard look at paper transfer. Is it close to a PM cycle?

              using OEM toner for all colors, got a slight gray haze on background and still lines on regular paper when paper tray is set to normal paper. but when paper tray is set to thick 1 it is better and most lines are gone. just changed ts belt and cleaning parts but ts rollers(all) are old. went there yesterday and re-cleaned everything around drums including optics and did an auto color reg adjust, it made my blacks go from gray to black but did not help the background or lines.
              can you tell me what changes when set to thick 1 or normal on paper with charges and bias and heat and speed?
              i tried changing exp and print driver settings and nothing changes the CQ when set to normal paper.
              I am going to change the black drum and cleaning parts and maybe developer.

                  Fusing temp and paper transfer charge should change. After replacing all those parts be sure to run programs 3820-1 and 2 procon adjustments.
