Abstract
Methods for operating a development station are provided. In one aspect a method comprises the steps of: applying a first force at a first end of an auger and a second force at a second end of the auger with the first force and the second force being sufficient to rotate the auger against a drag exerted by the developer and the replenishment toner. Both the first force and the second force are less than a third force applied to a single driven end of an alternative auger to rotate the alternative auger against the drag and wherein the auger has a first yield strength at the first end and a second yield strength at the second end that are less than a third yield strength required to receive the third force at the driven end of the alternative auger.
