Abstract
A reproduction apparatus that has an image-bearing member and an image transfer member includes a first drive assembly for driving the image-bearing member at a desired process velocity V1, and a second and separate drive assembly, including a DC servo motor, for driving the image transfer member in synchronization with the image-bearing member. The reproduction apparatus also includes a mechanism for engaging and disengaging the DC servo motor relative to the transfer member, first and second encoders for measuring in encoder counts the movements of the transfer member and of the image-bearing member, and controls including a logic and control unit that is connected to the encoders and to the servo motor for monitoring and controlling the operations of the reproduction apparatus. The reproduction apparatus further includes passive assembly for moving the transfer member at the process velocity when the servo motor is disengaged from the transfer member.
