A printing system comprises a printhead to eject a print fluid to a deposition region. A movable support surface, such as a belt, is used to transport print media through the deposition region, with the print media being held against the movable support surface by vacuum suction through holes in the movable support surface. A media registration device loads print media onto the movable support surface and registers the print media to a location of the movable support surface. The movable support surface comprises no-suction-regions in which the vacuum suction through the movable support surface is prevented. The no-suction regions extend across the width of the movable support surface in a cross-process direction and are arranged at predetermined intervals along the process direction. The control system causes the media registration device to register each of the print media relative to a respective one of the no-suction-regions.

A printing system comprises printheads to eject ink to a deposition region. Print media are held by vacuum suction against a movable support surface, which moves over a vacuum platen. The vacuum platen comprises platen holes through which the vacuum suction is communicated. An airflow control system comprises airflow zones, each comprising a group of the platen holes, a duct, and a valve, the duct and the valve being arranged to selectively control vacuum suction through the group of the platen holes. For each of the printheads, at least one of the airflow zones is located under the respective printhead. Thus, airflow through platen holes under the printheads can be selectively controlled by selectively controlling the vacuum suction in the airflow zones.

A printing system comprises a printhead to eject ink through an opening in a carrier plate to a deposition region. A print medium is held against a movable support surface by vacuum suction communicated through platen holes of a vacuum platen and transported through the deposition region. An airflow control system comprises upstream and downstream valves associated with the printhead, individually addressable channels for the vacuum platen, or both. The upstream and downstream valves are arranged to selectively block and allow airflow through an upstream side or a downstream side, respectively, of the opening in the carrier plate. Actuation of the upstream and downstream valves may be controlled based on a location of the print medium. The channels are arranged to selectively control the supply of vacuum suction to respectively corresponding columns of platen holes. Actuation of the channels may be controlled based on a size of the print medium.

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.

A recording device includes a recording unit, a support portion for supporting a recording medium, a transport path for transporting the recording medium, a recording medium holding unit for holding a roll body and supplying the recording medium, and a frame for holding thereof, wherein the frame includes a lower frame extending along an X direction and a Y direction, a pair of side frames extending along a Z direction and the Y direction, each including a lower end fixed to the lower frame and upright in the Z direction, and disposed at a predetermined interval in the X direction, and

a base frame held between the pare of side frames and including four wall surfaces extending in the X direction, and functional components related to recording of the recording unit are disposed inside the four wall surfaces.

An inkjet recording apparatus includes a sheet conveyance portion, a pair of registration rollers, a recording portion, a plate portion, a suction roller, and an exhaust portion. The exhaust portion is disposed over an area from upstream of the recording portion to upstream of the pair of registration rollers with respect to the sheet conveyance direction and sucks air from above the conveyance belt and the plate portion in the direction away from the conveyance belt. The exhaust portion includes an exhaust hood and an exhaust fan. The exhaust fan guides the air in the exhaust hood through an air inlet into a recording potion housing and then passes the air through an exhaust outlet to discharge it via an air flow passage.

Apparatus, methods, and systems for a vacuum conveyor for inkjet printing with adjustment to the covered area are disclosed. In some embodiments, a controller of a vacuum conveyor expands first one or more actuators of multiple first actuators of a substrate transportation system to decrease a suction width of an area of suction provided by the vacuum conveyor in accordance with a substrate width of a substrate being inkjet printed using the vacuum conveyor. A second one or more actuators of the multiple first actuators being retracted. The controller retracts multiple second actuators of the vacuum conveyor to increase the suction length of the area of suction while the substrate transportation system moves the substrate along the vacuum conveyor for inkjet printing of the substrate. The controller expands the retracted actuators of the multiple first actuators to increase the suction length as the substrates exit the vacuum conveyor.

A marker transport system and a method of operating the marker transport system. A group of print bars is located with respect to a marker transport platen and a marker transport belt. A vacuum source and a pneumatic solenoid block are associated with the marker transport platen. The marker transport platen includes airflow sections divided into process-direction slots and cross-section direction slots. The cross-section direction slots are located beneath the print bars and are connected to the vacuum source via the pneumatic solenoid block, which facilitates an individual control of each of the cross-process direction slots. Pneumatic valves are associated with the pneumatic solenoid block, which supplies a flow of vacuum to the cross-process direction vacuum slots. The pneumatic vales can be timed to allow the vacuum to be present when a sheet is present over a corresponding vacuum slot among the process-direction slots and the cross-section direction slots.

A printer includes a recording unit, a glue belt, a feeding unit, a suction unit, and a duct unit. The recording unit performs recording on a medium. The glue belt includes a support face capable of supporting the medium. The feeding unit feeds air toward the support face. The suction unit sucks air flowing from the support face. Air discharged from the suction unit flows through the duct unit. The duct unit is provided with an opening portion that adjusts a pressure difference between a pressure inside the duct unit and a pressure outside the duct unit.

A method of editing a print job to be printed on a flatbed printer including a flatbed surface for placing a piece of media to be printed upon, the flatbed surface having a vacuum zone connected to a vacuum source for attracting the piece of media to the flatbed surface, is performed on a job editor including a processor and a display. The processor performs the steps of: reading vacuum zone data specifying at least a size of the vacuum zone; constructing and displaying an image of the vacuum zone on the basis of the vacuum zone data; and superposing, on the display, an image to be printed and the image of the vacuum zone.
