Abstract
An apparatus compensates for mechanical disturbances during a print process by adjusting the generation of image generating head actuation signals in anticipation of a mechanical disturbance. The apparatus includes a printer controller for generating signals to coordinate movement of components with a rotating image receiver in a printer and for generating data identifying a process disturbance arising from interaction of the rotating image receiver with the components and an expected time for the process disturbance, a process disturbance compensator for generating a process disturbance compensation signal that corresponds to the process disturbance identification and timing data, and an image generating head controller for adjusting an image generating head actuation signal with the process disturbance compensation signal.
