A bearing plate for rotably supporting a photoconductor drum having a center shaft according to one exemplary embodiment includes a body having a first side, a second side, and an edge surface between the first and second sides. A center hole extends through the body for rotably receiving an end of the center shaft and positionally referencing an outer surface of the photoconductor drum to a center axis of the center hole. A support arm extends from the body in a non-radial direction. The support arm has a mounting surface for receiving an additional component positionally referenced to the center axis. An assembly for use in an image forming device according to one embodiment includes a photoconductor drum having a center shaft and a pair of substantially identical bearing plates mounted on opposite ends of the photoconductor drum. The bearing plates are translated from one another and have identical orientations.

A single manually operated mode selector lever controls selection of a push, pull or park mode of operation of a form feed tractor in a printer. The lever controls a cam which moves a spring-biased tractor drive shaft axially so that a gear on the drive shaft selectively engages a first gear which drives the shaft in a first direction, a second gear which drives the shaft in a second direction, or engages no gear so that the drive shaft is not driven. The form feed tractors are mounted on the drive shaft so that the shaft may move along its axis relative to the tractors or the tractors may be pivoted relative to the shaft. The mode selector lever also controls a mechanism which applies a force to a tractor plate so as to pivot the tractors about the drive shaft, thereby changing the orientation of the tractors relative to the platen. The force applied to the tractor plate is also transmitted to pressure or pinch rolls in the pull mode to relieve constraint on movement of the forms.
