Genuine Ricoh MPC5000 Complete Black Process Unit. Includes Drum & Developer D0292256. MPC4000. Please note that when you open the item after receiving it, it will not be perfectly clean, as there is toner in the process unit, and in shipping, it will get dirty. All that is needed is to gently wipe the plastic down, while NOT touching the drum. The drum will clean itself once the machine is operating.
