  • Enhanced toner throughput agitator configuration for a customer replaceable unit
    Patent number: 9116499
    Abstract: A customer replaceable unit for a printer includes a toner reclaim system that has a spring-like wire attached to and surrounding the bottom half of a toner agitator. As the agitator is rotated by a cleaner auger through a crankshaft connection, the spring compresses and relaxes with every revolution. This creates small vibrations which help move toner in a downward direction with the assistance of gravity into a developer sump.
