Abstract
An improved electrophotographic toning station for use in an electrophotographic printer includes a unitary bearing cap and tension sprocket assembly that allows for the use an intermediate drive chain to drive a primary drive sprocket that drives the toning shell at high speed, through a primary drive chain. A unitary bearing cap and tension sprocket assembly that allows the tension sprocket assembly to be properly located relative to the intermediate and primary drive sprockets, such that the components of the toning station may be adjusted relative to each other without interference from the tension sprocket assembly.
Claims21
An electrophotographic development station comprising a bearing cap body, sprockets attached to the bearing cap body, a tension sprocket assembly secured to the bearing cap body, and a drive chain around the sprockets and the tension sprocket assembly, wherein the drive chain, tension sprocket assembly, the sprockets and the bearing cap body are moveable as a unit without changing a tension in the drive chain.
An electrophotographic printer, comprising:
- an electrophotographic development station comprising a bearing cap body,
- sprockets attached to the bearing cap body, a tension sprocket assembly secured to the bearing cap body, and
- a drive chain around the sprockets and the tension sprocket assembly, wherein the drive chain, the tension sprocket assembly, the sprockets and the bearing cap body are moveable as a unit without changing a tension in the drive chain.
An electrophotographic development station method of operation comprising tensioning a drive chain disposed around sprockets attached to a bearing cap body with a tension sprocket assembly secured to the bearing cap body, wherein the drive chain, the tension sprocket assembly, the sprockets and the bearing cap body are moveable as a unit without changing a tension in the drive chain.
