  • Publication number: 20220314646
    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 moving 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 a damper and an actuator configured to move the damper along a cross-process direction. The damper blocks airflow through a subset of the holes along a side of the media transport device, the subset varying based on a position of the damper. The damper is moved to change the subset of the holes blocked by the damper based on a size of the print medium.

  • Publication number: 20220314665
    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 a vacuum platen 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 dampers that are moveable along a direction perpendicular to the vacuum platen 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 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.

  • Publication number: 20220305816
    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 printhead module comprising a plurality of printheads to eject a print fluid to a deposition region. The media transport device holds a print medium against a movable support surface by vacuum suction and transports the print medium through the deposition region. The air flow control system is arranged to flow air toward the movable support surface at locations upstream and downstream of the printhead module, based on a location of a print medium relative to the printhead module.

  • Publication number: 20220234358
    Abstract: A system includes a processor that executes computer executable components stored in a memory. The system includes a first component to receive data generated by at least one sensor. The system further includes a second component to generate an array that determines between activating one of a purge routine and a diagnostic routine on a printhead based on the array. The array is a function of the data. The system further includes a control component operable to selectively activate the purge routine on the printhead based on the determination.

  • Patent number: 11117386
    Abstract: An inlet seal, an outlet seal, and a piston are connected to a shaft. The inlet seal seals an ink inlet of an ink reservoir. The outlet seal seals an ink outlet of the ink reservoir. Also, the piston is within a cylinder. The inlet seal, the outlet seal, and the piston all move with the shaft. A biasing member contacts the piston to bias the piston in a first direction. Pressurized air simultaneously provided to the cylinder and to the ink reservoir biases the piston in a second direction, opposite the first direction, and pressurizes ink within the ink reservoir. Moving the shaft in the first direction does not seal the ink inlet but does seal the ink outlet. Moving the shaft in the second direction seals the ink inlet but does not seal the ink outlet, thus allowing the pressurized ink out from the ink reservoir.

  • Patent number: 11052662
    Abstract: Inkjet printhead cleaning methods and systems control an articulation structure (that is connected to a wiper blade) to move the wiper blade to contact an inkjet printhead to wipe the inkjet printhead. These methods/systems further control the articulation structure to move the wiper blade to contact a blade cleaning structure to clean the wiper blade. The blade cleaning structure comprises a fluid manifold and bundles of fibers mounted in brush openings of the fluid manifold, and cleaning fluid is in the fluid manifold. The mounting ends of the bundles of fibers are mounted in the brush openings of the fluid manifold and the cleaning ends of the bundles of fibers are positioned to contact the wiper blade. The blade cleaning structure is positioned so as to gravity feed the cleaning fluid from the mounting ends of the fibers to the cleaning ends of the fibers.

  • Patent number: 10350908
    Abstract: An object printing system facilitates the printing of articles of manufacture. The system includes at least one printhead, a transfer device, an ultraviolet (UV) radiator, a pressurized gas source operatively connected to the transfer device, a plurality of actuators, and a controller. The controller is configured to operate the at least one printhead to form an image on a substrate, move the substrate bearing the image past the UV radiator as the controller operates the UV radiator to cure the ejected marking material partially to prevent ink movement, and operates the pressurized gas source to conform the substrate and partially cured ejected material to a shape corresponding to a surface of an object placed on the substrate to transfer the partially cured marking material onto the surface of the object. The transfer device can be an inflatable bladder or a molded vacuum chamber.

  • Patent number: 10213958
    Abstract: 3-D printers include a transfuse station having at least one roller on one side of the ITB supporting the ITB, and a transmission device on the same side of the ITB. A platen is included that moves relative to the ITB. The ITB electrostatically transfers a layer made up of the different color build materials and the support material to the platen each time the platen contacts the other side of the ITB at the transfuse station (the side of the ITB opposite the transfuse station roller and transmission device) using vibration and charge devices; and this successively forms multiple layers of the build materials and the support material on the platen.

  • Patent number: 8579102
    Abstract: A belt cleaning system to clean a conveyor belt carrier surface includes a first cleaning assembly having a cleaning web sub-assembly. The cleaning web sub-assembly includes a supply roller, a take-up roller, a cleaning web and an applicator. The cleaning web extends from a supply of clean cleaning web wound on the supply roller to the take-up roller. The applicator is disposed intermediate the supply roller and the take-up roller to bias the cleaning web into contact with the conveyor belt carrier surface. The belt cleaning system may also include a second cleaning assembly positioned after the first cleaning assembly in the direction of travel of the conveyor belt. The cleaning webs of the first and second cleaning web sub-assemblies may be dry or wetted with a cleaning liquid.
