    FS-4020, stupid question from a noob....

    Changed in a FS-4020 the drum unit with a DK 320 Drum Kit. Now, after 50K, fine lines are appearing on the prints which are most likely caused by the charge roller since the drum surface looks good.

    20150518_102406.jpg

    I have two questions please:

    A)
    Is it possible that the drum kit DK-320 came without charge roller and that I used the old one? (*slap face* I know, I know, utmost stupid not to know this anymore but I think the brain damage from years of sniffing toner and ozone start to take its toll.....)

    B)
    In case the drum kit came with a new charge roller how can these damages develop and why on the charge roller and not on the drum itself too?

      A) You did not use the old one. 50k is more than enough for charge roller to build some ozone, and get dirty (paper dust from low quality paper mostly). It can become completely grey-white after some time if not cleaned. With OEM toner that drum will last you over 300k (i've had plenty passing 500k before they had to be replaced).

      B) The drum roller itself gets cleaned. First you have cleaning blade behind it that wipes everything off. Also the OEM toner powder itself has ceramic particles in it and it's polishing the drum making it last longer than any other manufacturer in this segment.

          Thanks Kyo Fan, but why the damage/markings on the charge roller if its an almost new one? There is no dirt but the surface has lines in it. See picture.

              This is what we try first in our tech room for poor print quality on these printers ;

              Remove the MC-320 from the Drum :
              Take a plain cotton rag , lightly moistened with plain WATER .
              Scrub the Charge Roller to clean all the debris/lines off .
              Dry the Charge Roller , re-install on the Drum and test the operation.
              "The Serenity Prayer" . . .
              God grant me the serenity to accept stupid people , the courage to not waste my time and energy on them , and the wisdom to know that I cannot fix STUPID .

                  A) New drum units DO come with the main charge on them.

                  B) Very common issue to clean charge roller ever 50k. I agree, water is best to clean them and that paper quality or aftermarket toner will have impact on how often they need cleaned. I have a hospital with 40-50 kyocera printers and we use aftermarket toner. Some still have lines after cleaning so I'll replace just the main charge roller before drum reaches end of life.

                      Kyo fan and D_L_P have it exactly right. It's very common for these charge rollers to build up with ozone. Clean when you can, replace when you it doesn't help.

                      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.

                          Yep common to have to clean them due to lines/streak on page. This is the highest percentage of the calls I have on this model. I think some of the aftermarket toner causes it to be much worse. Good thing is you buy the charge roller separately at least.

                              Hello,
                              I clean up the Kyocera charge rollers by cleaning foam (Interflon) for monitor glass and plast. You can also easily try cleaning foam made by another manufacturer, but I got best result by Interflon cleaning foam.
                              I have good experience by this method. I also recommend you to overclean the roller by clean water !
                              Of course it is needed to clean roller disassembled out of MC chassis.
                              Bye.

                                  Guys the roller is not only (if at all) dirty but has grooves in it. So the surface is damaged. See the picture please.

                                              Sorry, I missed that it was damaged. At a glance it just seemed dirty.

                                              Since damage is not on the drum I'd suspect the cleaning brush behind the charge roller is probably not turning or has something very small on it that rubbed a groove in the charge roller. Not unusual to see grooves after a lot of clicks (+150k), but I'd just replace the mc-320. In my experience I haven't seen grooves comeback with a new charger roller.

                                                      Detrition charge roll after 50K printout is possible. Specially in a case of short print jobs (1-2page per print job)
                                                      My experience is about 100k (usually 1x cleaning is needed).
