Abstract
A prime mover is connected to a drive train in a printer to provide incremental or intermittent motion to the paper and to the hammer bank in a time sharing manner wherein the output of a closed loop control mode having a switching amplifier and a feedback circuit utilizing pulse width modulated signals operate the system under static conditions. The drive train includes the use of a planetary gear head and electro-magnetic friction brakes for transducing the output from the prime mover to the two loads. Alternate transducing means include the use of two clutches, or a planetary gear head and band brakes.
