ABSTRACT:
A duplex electrophotographic device has a driving apparatus that is constructed using only one motor to drive the various gears and rollers of the electrophotographic apparatus. A main gear is driven by the motor. The main gear is engaged with a set of gears that are mounted on a rod that is pivotally mounted inside of the housing of the electrophotographic device. A solenoid is attached to one end of the rod to move the set of gears between a first and a second position. When the set of gears is in a first position a first assembly is engaged with the set of gears. This assembly rotates a first plurality of rollers to transport a sheet of paper in a first direction. While the set of gears is in a second position, the set of gears is engaged with a second assembly that rotates both a first and second plurality of rollers in a second direction.
