Abstract: A printing system comprises an ink deposition assembly, a media transport device, and an airflow control system. The ink deposition assembly comprises printheads to deposit a print fluid, such as ink, on print media, such as paper, transported through a deposition region. The media transport device holds the print media 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 the deposition region. The airflow control system comprises one or more valves that are actuatable between an open state and a closed state, each valve blocking a subset of the holes in the closed state. The airflow control system also comprises one or more actuators to actuate the valve(s). The actuator(s) selectively actuate the valve(s) between the open and closed states based on a position of an inter-media zone between adjacent print media.

Abstract: A printing system comprises an ink deposition assembly and a media transport assembly. The ink deposition assembly comprises a printhead arranged to eject a print fluid to a deposition region of the ink deposition assembly. The media transport assembly comprises a vacuum source and a movable support surface. The movable support surface comprises valves having holes through the media support surface. The media transport assembly is configured to hold one or more print media against the movable support surface by vacuum suction communicated from the vacuum source through valves. The valves are each configured to transition between a closed state in which airflow through the hole of the respective valve is prevented and an open state in which airflow through the hole of the respective valve is allowed.

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.

Abstract: A printing system comprises a print fluid deposition assembly, a media transport device, and an air flow control system. The print fluid deposition assembly comprises a carrier plate and a printhead arranged to eject a print fluid through an opening of the carrier plate to a deposition region. The media transport device holds a print medium against the movable support surface by vacuum suction and transports the print medium through the deposition region. The air flow control system comprises an air supply unit comprising air flow guide structure extending into the opening of the carrier plate between the carrier plate and the printhead to flow air through the opening. The air flow control system controls the air supply unit to selectively flow the air based on a location of a print medium relative to the printhead.

The print fluid deposition assembly comprises a carrier plate and a printhead arranged to eject a print fluid through an opening of the carrier plate to a deposition region. The media transport device comprises a movable support surface to transport a print medium along a process direction through the deposition region, the media transport device holding the print medium against the movable support surface by vacuum suction. The air flow control system is arranged to selectively flow air through the opening of the carrier plate between the carrier plate and the printhead based on a location of a print medium transported by the media transport device relative to the printhead.
