    One Red line

    Hi,

    KM Bizhub Pro C6000l - bought for learning and starting point for book printing. I'm a little addicted - to printing and creating process from start to finish.


    The red line manifested itself on some prints with magenta color.

    1. clening ( it was done - one time but is here again)
    2. replace the drum & corona
    3. developer


    Happy printing ...

      99% of the time that line is just a dirty corona wire or grid.
      just swap coronas next time and see if the line follows the parts.
      same for drums.
      might save you a ton of money narrowing down the exact part.
      We know a thing or two because we've seen a thing or two.
      The medication helps though...

          Haven't worked on these big boys but I can't imagine a super fine line like this is caused by a charge grid/corona. I would have guesses it's a groove on the drum surface.

              its very common, even a fleck of dust on the grid or wire can cause that exact width line.

                  I managed to clean up all corona wire and now is read line gone.

                  Also I change the developer unit and developer for Yellow.

                  Happy printing this weekend.

                  It's really great to have some support and respond to this topic.
                  Thank you!
