    Stains on copy model 308e

    Good evening, I installed a konica minolta model 308e, after about 80,000 copies it has spots only on the first printed sheet, the rest are clean.
    every time I print a single sheet it stains, while if I print 20 sheets only the first one gets stained.

    Kindly someone can tell me what I can do.
    thank you

    Could you upload a sample? There are several things that could cause this, and a sample picture could be helpful.

      Try it without filters at the back of machine. Also make sure firmware is up to date.

        I've seen this several times and was always due to loss of developer. You will have to determine what color is low on developer then either replace that developer unit or much less expensive replace just the developer powder with aftermarket developer. Also make sure you replace any drums that are at 0% or they will short out and cause the developer to deplete again.

          I would respectfully disagree. Besides this is mono color machine 8e series. They are prone to premature fuser/drum failure not to developer depletion.

            I missed it was a color model. Regardless the several times I had 1st page out "only" with quality issues it was usually the black developer loss and / or aftermarket toner. Usually after machine sits for awhile the 1st page "only" will look like bad fuser unit with repeat image, etc etc.. 2nd page and after the pages will be fine.

                  I would still look at Drum & developer. Although check fuser just to be sure but with 80k shouldn't be bad unless running all thick stock.

                  Are you using aftermarket toner? What % is drum?

                      I'm leaning towards drum cleaning myself, with a side order of primary charge contamination. The drum could have failed at 80K conceivably. Certainly it's a good place to start. =^..^=
                      If you'd like a serious answer to your request:
                      1) demonstrate that you've read the manual
                      2) demonstrate that you made some attempt to fix it.
                      3) if you're going to ask about jams include the jam code.
                      4) if you're going to ask about an error code include the error code.
                      5) You are the person onsite. Only you can make observations.

                        I'm agreeing with you on this one. We had a couple OEM 8-series drums a about 2 years ago with a cleaning blade issue that looked just like that. The lead edge of the smear had that arched look to it like in the sample. The only thing that the cleaning blade wouldn't explain are the couple lines at the top of the sample page.

                        At the end of a job the drum is rotated backward ever so slightly. I assume this is to "clean" the blade, but I never bothered to look into why. In any case, on the drums we had the problem with it seemed like the blade was slightly flipping backwards during this reversal of the drum. When the next job came around the blade would have to flip back into its proper place, resulting in the arched smear on the very first page of every job. We tried using some drum powder on the drums, and it did work to clear up the smears for the next couple of jobs, but ultimately would return. In the end we had to replace the drums.

                          I had several drums do this. Pops up once in a while. New drum takes care of it

                            Never had it on a "4" series so if the drum as suspected it's probably that damn PCR !

                              I agree with Gift , Looks like it might be the transfer belt cleaning unit
