Patent ID: 7310108

Claim:
A printing system comprising: a first marking engine; a second marking engine; the first and second marking engines being operatively connected to each other for printing images onto print media; a print media transport system which collects printed media from the first and second marking engines, the print media transport system including a common paper path which receives printed media from the first and second marking engines; a sensor element, associated with the common paper path, for measuring an image quality parameter of printed media traveling thereon and generating a control signal therefrom; a movable baffle, adjacent the sensor element, for selectively reducing a width of the common paper path; and an image quality controller, in communication with the sensor element, for adjusting image quality parameters in at least one of the first marking engine and second marking engine based on the control signal to reduce a variation in an image quality characteristic of printed images produced by the first and second marking engines.
