ABSTRACT:
A shaft assembly, including a main shaft, is used with a postage meter of the type including a base supporting the main shaft. A printhead is mounted to the outer end of the main shaft so the main shaft and printhead rotate together. The main shaft has a flat surface against which a number of elongate value rods are mounted parallel to the main shaft axis. The outer ends of the value rods are coupled to the printhead to operate the printing elements of the printhead. The inner ends of the value rods are connected to stepper motor drives, mounted to the base, to move the value rods axially. Bearings, mounted to the main shaft, radially position the main shaft relative to the base. At least one of the bearings is fixed to a chosen axial position along the main shaft so that such bearing, when mounted to the base, also axially positions the main shaft relative to the base.
