Feedback control for receiver member in-track registration in an

Abstract

Feedback control for receiver member in-track registration for immediacy of registration error correction and improved long term in-track registration accuracy. In an electrostatographic reproduction apparatus or the like, a receiver member is fed at a preselected time from a supply and transported along a travel path, including a registration mechanism adapted to selectively intercept the travel path. The receiver member is stopped at the intercept position, and a desired dwell time for the receiver member at the intercept position, prior to actuation of the registration mechanism, is established. After expiration of the dwell time, the registration mechanism is actuated to advance the receiver member from the intercept position into association with a marking particle developed image. the receiver member is sensed at a predetermined location downstream of the registration mechanism and a signal indicative thereof is provided. In response to the signal indicative of sensing the receiver member at the downstream location, the time for sensing a receiver member is determined, and such determined time is compared to an absolute reproduction apparatus time expected for sensing of a receiver member. Thereafter, in response to such comparison, feedback is provided to alter the time for actuating the registration mechanism and, based on such altered actuation time, altering starting of the dwell period.
