  • Patent number: 12005700
    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.

  • Patent number: 11850842
    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.

  • Patent number: 11839916
    Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with an orifice cleaning system that removes metal drops that have adhered to a plate, an orifice in the plate, and a nozzle ejecting melted metal drops through the orifice during object forming operations. The orifice cleaning system includes an orifice cleaning tool that consists essentially of a soft carbon material, such as graphite. The orifice cleaning tool is configured with a handle that is gripped by an articulated arm to move the orifice cleaning tool against the plate, the orifice, and a portion of the nozzle at the orifice.

  • Patent number: 11801674
    Abstract: An optical gloss meter above an imaging member surface measures fountain solution surface gloss on the imaging member surface in real-time during a printing operation. The measured gloss corresponds to a thickness of the fountain solution layer and may be used in a feedback loop to actively control fountain solution layer thickness by adjusting the volumetric feed rate of fountain solution added onto the imaging member surface during a printing operation to reach a desired uniform thickness for the printing. This fountain solution monitoring system may be fully automated.

  • Patent number: 11772391
    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.

  • Publication number: 20230256749
    Abstract: A dross extraction system for a printer is disclosed. The dross extraction system includes an ejector defining an inner cavity associated therewith, the inner cavity retaining a liquid printing material. The dross extraction system also includes an inlet coupled to the inner cavity and a conduit external to the ejector having a distal opening, positionable to contact the liquid printing material to attract dross therein, thereby extracting dross from the liquid printing material when a negative pressure is introduced between an internal volume of the conduit and the dross.

  • Patent number: 11376840
    Abstract: Examples of the preferred embodiments use printed content (e.g., halftones, difference in grayscale or darkness) to determine thickness of fountain solution applied by a fountain solution applicator on an imaging member surface and/or determine image forming device real-time image forming modifications for subsequent printings. For example, in real-time during the printing of a print job, a sensor may measure halftones or grayscale differences between printed content and non-printed content of a current printing on print substrate. Based on this measurement of printed content output from the image forming device, the image forming device may adjust image forming (e.g., fountain solution deposition flow rate, imaging member rotation speed) to reach or maintain a preferred fountain solution thickness on the imaging member surface for subsequent (e.g., next) printings of the print job.
