Abstract
A printing system comprises a media transport device which holds print media, such as paper, against a movable support surface, such as a belt, by vacuum suction through holes in the media transport device and transports the print media though a deposition region of one or more printheads, which deposit a print fluid, such as ink, on the print media. The printing system comprises an airflow control device comprising one or more dampers that are moveable in a cross-process direction between an undeployed configuration and a deployed configuration, each damper blocking at least one row of the holes in the deployed configuration. The airflow control device also comprises one or more actuators to move the damper(s). The actuator(s) are controlled to selectively move the damper(s) between the undeployed and deployed configuration based on a position of an inter-media zone between adjacent print media held against the movable support surface.
