    Hi there!
    End user is struggling with a KM C227 from some time now. The machine was constantly printing with a magenta hue on all colour pages and the calibration procedures helped a bit whenever the issue was present.
    All drums and developing units were changed in the past as they were approaching end of life, but the magenta issue came back after a while and it consumed extra toner. There was also a lot of ejected toner inside the machine.

    Now, the machine prints thick vertical lines which seem to be composed of Y, C BK and some M. I've attached a sample print.

    Any idea what could be causing the issue? Drums and belt look ok. Possibly the laser unit is dirty?

    Moreover, the machine also shows and error C-0202 for Tray 1 . I found some jammed paper in the lift mechanism for Tray 1, but it seems that the motor or sensor is damaged.

    Troublesome machine, this one
    Nope. Its not gonna be a dirty laser slit glass.

      In a nutshell the copier is writing to the drum when its not suppose to be is a clue.

        About the copy quality errors, I didn't see anyone ask whether there might be generic toner in the machine?

          Because this thread is 4 years old.
          Necroposting.
          Likely settled a long long time ago.
          We know a thing or two because we've seen a thing or two.
          The medication helps though...
