ABSTRACT:
A replacement roller cartridge for a cut sheet retard feeder. The cartridge assembly includes a feed roll, a nudger roll, and a retard roll aligned so that the axis of rotation are substantially in the same plane within an articulated frame. The frame is inserted into the feed head and pivoted into an active position. Upon insertion into the feed head, the retard roll is captured by a separate retard bracket so that when the feed head is pivoted into the active position the retard roll is withdrawn from the frame and forms a feed nip with the feed roll. The articulated frame is geared so that the frame folds back against itself to provide a very compact unit. A gear train is provided on both sides of the cartridge to drive the feed roll and the nudger roll. The cartridge assembly provides a low cost, easily replaceable unit that eliminates the need for a service technician to replace worn feed rolls. The design is also adaptable for use in various types of sheet and document feeders and can be used throughout a printing machine. The preassembled cartridge also obviates the need for a technician to calibrate or adjust the positions of the feed rolls as they are locked into position upon insertion and rotation of the cartridge frame into the feed head.
