    [CQ] Bizhub C280 (CQ)

    I'm having problems with a C280 machines for a few days now. The problem is when a color copy or color print would come out, you can see a very faint background of yellow. If you look closely at the background, you can see lines. The image units have been replaced, and transfer belt roller cleaner have been vacuumed from excess waste toner. Also to point out, after a copy, I noticed that there is yellow toner that is hazed on the transfer belt. Any ideas?

      Have you done the gradation?
      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.

              Yellow is the first color to be put on so it will be the last to come off. (the transfer belt) So I would imagine that some would be left on the belt after transfer to paper. (I believe it goes YMCK on that box)
              Color is not 4 times harder... it's 65,000 times harder. They call it "TECH MODE" for a reason. I have manual's and firmware for ya, course... you are going to have to earn it.
