        But seriously, Kyocera needs to do something about their bulletin search. This is literally how the bulletin comes back when I searched "H139" what cryptic garbage. You would think DEFECTIVE DRUMS could earn a bulletin spot on the machine's main resource page.

          Agreed I hate the download center.

            some ricoh drums were supposed to last 100k ( K&color) they were only making it 30-50k until I showed the boss this trick... saved him money and I got a lil spiff in my next paycheck.
            Do you apply the Nu-Finish with the charge roller in place or do you remove it from the drum assymble. Any specific type of towel that you use to buff it out with?

              Sorry explained fully in other forums.
              Yes, remove from drum. Coat well.. let dry (1min) buff with micro cloth ( or soft) repeat 2 times.. reassemble.
              It will remove build up..not scores or bumps in roller coating.

                I too have seen this and replaced the drum and it came back, so i cleaned it off the drum and charge roller. Does anyone know how long this lasts if you clean it off? Also , is the bulletin saying that they made changes to the spacing and to change in a new drum? I mean i changed the drum first with a new one and it didn't last that long. This was on a 6235cidn.

                  Wow! this is an old thread!

                  The internal temperature inside the machine closest to the fuser is warm enough to fuse the loose toner in the black drum cleaning unit to the black drum, in bands. The new style drums do not help (do nothing to decrease the internal temperature of the machine). There are no fan settings to change.

                  It happens especially on low volume devices that have energy saver set to 240min. The only real long term answer is to make the machine sleep within 5 minutes or less.

                  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 sorry to disagree with you, but I have had seen systems with 1 minute Energy Saver Time and dash mark problem.
                    With the special drum there are only less cases.
                    Sometimes the problem is solved, but sometimes it comes back, unfortunately I don't know why.
                    Since it occurs on newer and older systems, the new environment sensor mounting position can also be ruled out.

                    I am already looking forward to the first call for Virgo with drum dash marks.

                        Here you get it:
                        First joke:
                        From specs. KDC had written Virgo drums are dash mark compatible.... all 4 drums/ no more special drum for BK needed.
                        Strongly forbidden to use the special Mebius drum on color position, because of the stronger cleaning blade pressure.
                        Virgo Systems <45ppm are using same OPC drum surface layer as previous model.
                        On Mebius systems we have had a lot of drum film decreasing/ mostly beginning with yellow drum. (far away from fuser unit)
                        Next joke:
                        KDC answer to one of our requests:
                        The cabin temperature on the status is high at 30 degrees Celsius, so I want to check if there is any factor in the installation environment.
                        (Is the space near the intake fan narrow, or is it not possible to prop up files, etc.)
                        The higher the temperature, the faster dash marks will appear or drum layer will decrease.
                        In order to prevent the waste toner from solidifying due to a raise in the temperature inside the main unit.

                            This is a known issue. They have come out with a DK-5140(A) to resolve, only to be used in black. Hope this helps if you haven't already discovered this information.

                              unfortunately, i have to fight on several fronts because kdc does not learn from past mistakes.
                              when you read some of their answers, you get gray hairs and just wondering.
                              (I already have gray hairs and would like to kick their butts more often, but unfortunately they are too far away).
