    Re: big problem of Konica Minolta C6500

    Hey men...

    what is the status of this problem?

    check mine.. i guess i have the same problem.. but mine is a bit different, check the files.. dont mind the dirt on the scanners flatbed.
    paper is kromkote 210gsm, test pattern 53 at 155 value.the left side of the image is the leading edge and the left side is the trailing edge.
    Maybe if you guys ever encounter this, it would be a great help..

    btw, black has new dev unit, dev, drum and charge, new intermediate Unit, new 2nd transfer roller.

    see the outside,it is different with other area.it is hard to express,the outside of the copy is like swept by something.
    I change the drum,developer,developing unit,charging unit,transfer unit and clean the black laser unit,no change!

    any suggestion?
    Did you check the lower transfer roller on the transfer belt?
    Had a similar problem once where the bearing on the inside wasn't spinning correctly and was causing a similar problem.
    Plus if i remember correctly theres a screw there in which you can adjust his pressure on front to back(could be mistaken about this though).

    EDIT:Just saw you said you changed the whole transfer belt unit?If so scrap my post.
    I don't like the new copier I just bought. It says "put face down" but every time I do it, it blinds my eyes.

    did you close the flip tab on the black developer unit after adding new developer at PM?...
    did you take the red screws out of the black drum?....

    i take it that all other colors but black are printing fine, that eliminates just about everything else....
