Abstract
A method and apparatus for controlling image defects associated with overdrive or underdrive, and variations thereof, in an electrostatographic machine. A speed modifying force is transmitted to a conformable member that deforms in a nip, thereby inducing strains in the surface of the member at the nip which cancel or controllably reduce the strains caused by engagement in the nip. The speed modifying force may be an externally applied drag force or torque, and may be applied using an open loop or a feedback system including an electromagnetic brake, a motor, etc. The speed modifying force may be applied to a conformable member forming the nip through a redundant linkage of the system that employs gears or other suitable mechanisms.
