    284e not adding toner and no code

    Hi and thanks to everyone in advance.I have worked on KM products since they were just Minolta. We have a couple of 4's that just don't add toner all of a sudden.The really odd part is we are not getting any codes for the deficiency(c-255?).Is their a perfect storm that can allow this to happen. I have a 224e b/w doing this as well as a c554e doing it only on yellow/cyan. Any and all advice would be appreciated. We don't want to just throw parts at it.

    How are you maintaining the machines? New OEM parts or are you rebuilding the units?
    Whatever

      And toner is?
      A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.
      Blessed are they who can laugh at themselves, for they shall never cease to be amused.

        These older models are getting to an age where they can have toner hopper issues, white bushings, etc.

          It's good to have some spare machines so you can take used parts from! That's how we do it mostly to keep the cost lower.
          Also depends on the client and the occasion, some clients might want to pay for a new part/unit so that's what you give them but if the machine is getting old you probably wouldn't want to put new parts as it will come to a point that the old copier will have to be replaced with a newer model.

            I recently had this issue, it was related to the toner hopper / white bushings, luckily i had an old junker to steal parts off. Try following some of the steps in this thread:

              I use oem supplies and have replaced bushings and motor. I just don't know how it allowed it to become so under toned and not code or ask to replace toner..

                I have seen it as low as 0.0 TCR and machine still was working and producing good test pages
                I was thinking along same line as you but go figure it. In my case white bushing solved problem though.

                  There is also a cotton bushing at the opposite end of the white bushing in the front on the same auger.
                  replace both as it well bind eventually at the back.
                  messy job so you need a vacuum.
