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.

Abstract: An electrophotographic printer having an improved flexible drive chain cover located to protect the toning shell drive chain from contamination with toner dust. The electrophotographic printer may include a rigid drive chain cover located adjacent the flexible drive chain guard and locate so that the flexible drive chain guard and the rigid drive chain overlap.

Abstract: An adjustment mechanism for setting up spacing of a development station for a reproduction apparatus within a desired tolerance range such that marking particles from the development station properly develop electrostatic images. The adjustment mechanism includes a datum member and a cam having a locating post for the development station extending from the cam. The datum member includes, for example, a bracket in the reproduction apparatus, and at least one pin attached to the bracket. The cam is adjustably associated with the datum member so as to selectively position the locating post a predetermined distance from the datum member. The adjustable cam includes, for example, a member defining a plurality of spaced openings, the openings capable of receiving the at least one pin of the datum member so as to position the locating post dependent upon which opening the at least one pin is received within.
