ABSTRACT OF THE DISCLOSURE As documents are moved serially past a servo motor-driven endor- ser, it endorses a stamp upon each. A transport signal dependent on docu- ment speed, and an endorser signal generated by an optical tachometer mounted to the servo motor, provide input to a frequency comparator. The output of the comparator is a control signal which controls the servo motor speed to adjust the endorser rotational surface velocity to equalization with the document speed. Logic circuitry sets the endorser at a zero angular position. Responsive to an endorse command, the endorser is acceler- ated to document speed, receives ink from a supply roller, then endorses the passing document. A counter and a digital comparator in cooperation with the tachometer signal completion of the endorsement whereupon the endorser is decelerated and placed in the zero position. Should a succeed- ing endorse command occur prior to complete deceleration, acceleration is resumed after a delay count given by a PROM and based upon the pulse count when the succeeding endorse command is received.
