Ricoh MP6055 drum/developer assembly rebuild

This video should give you an idea of what's involved in rebuilding a drum/developer assembly with a PM kit. The life expectancy of these parts is 160k. This machine has 111k, so it's a little premature for it to fail but not surprising.
It's important to at least replace the developer regularly or these machines can become very dirty.
I hope this video helps. Thanks a lot for watching.
