Abstract

Development stations are provided. A development station has a housing having a recirculation path and an auger being rotatable to move the developer along at least part of the recirculation path. A first actuator drives a first end of the auger and a second actuator drives a second end. A first sensor senses a rotational position of the first end while a second sensor senses a rotational position of the second end of the auger. An auger controller causes the actuators to act so that a first force and a second force rotate the auger against a drag. The first force and the second force are less than a third force to drive an alternative auger from a driven end. The auger has a first end yield strength and a second end yield strength that are less than a driven end yield strength of the alternative auger.
