Replace the toner supply unit (B0653111), waste toner vertical transport unit assembly (B0653554),

With gear replacement alone, the symptom will shortly reoccur. In addition, individual

replacement of the toner collection coil can be a dirty job at the customer location, and during

replacement, the waste toner may scatter about at the customers site. It is suggested to replace

the entire toner supply unit at the customer's location.
