  • Publication number: 20180281311
    Abstract: A print system and a method for curing marking material on an object using an active LED array in a three dimensional (3D) object printer are disclosed. For example, the print system includes a plurality of printheads, a curing light source comprising a plurality of light emitting diodes (LED) that are independently addressable, a movable member to hold an object, and a controller to control movement of the movable member to move the object past the array of printheads, to operate the plurality of printheads to eject the marking material onto the object as the object passes the two-dimensional array of printheads, to control movement of the movable member and to operate each one of the plurality of LEDs of the curing light source to apply energy in accordance with a shape of the object to cure the marking material.

  • Patent number: 10086626
    Abstract: What is disclosed is a system for registering an object in a direct-to-object print system and a direct-to-object print system configured to operatively use various embodiments of the registration system of the present invention. In one embodiment, the marking system comprises a registration panel with a plurality of registration markings. A camera captures an image of the object in the object holder and the registration panel. A processor receives the image and analyzes the image to determine a position of the object relative to the markings on the registration panel. The processor determines whether the object is registered. If the object is registered, a controller causes the object holder to move the object past the printhead. Otherwise, if the object is not properly registered then the processor prevents the object from being printed and communicates a notification to a user that the object in the object holder is not registered.

  • Patent number: 10067362
    Abstract: A switchable mirror system and method includes a laser imaging module including one or more lasers and one or more DMDs (Digital Micromirror Devices), and a switchable mirror component located in a path upstream from the DMD (or DMDs) to direct a laser from the DMD when there is pause in a printing operation facilitated by said laser imaging module. A non-mechanical and electronic switchable mirror is thus located in the laser path between an LDA (Laser Diode Array) and a DMD to divert energy out of the system and away from the DMD during periods of non-laser imaging without reducing or power down the laser system.

  • Publication number: 20180244028
    Abstract: A process for applying a release agent and pressure sensitive adhesive to cut sheet media to thereby eliminate a separate release liner. A silicone oil plus additive release layer is applied during fusing on a top surface of cut media and then UV cured. A pressure sensitive adhesive layer is applied next. The cut sheets are then stacked and a compressive force is applied that transfers the pressure sensitive adhesive from one sheet to another and helps hold the stack together.

  • Patent number: 10054857
    Abstract: A laser imaging system and method for printing includes a digital micromirror device and a switchable mirror element that acts as a clear lens element during the printing by the laser imaging system. A laser diode array provides a laser to the switchable mirror element in a laser path, wherein the switchable mirror element is located in the laser path between the laser diode array and the digital micromirror device to divert energy out of the system and away from the digital micromirror device during periods of non-laser imaging without reducing or powering down the laser system.

  • Patent number: 9981484
    Abstract: A method for applying flame treatments to a print surface on an object in an inkjet printer includes activating a hydrogen torch within the inkjet printer to generate a flame through a nozzle of the hydrogen torch and operating an actuator to move at least one of the print surface or the nozzle in a predetermined direction to apply the flame from the nozzle to the print surface. The method further includes adjusting a rate of fuel flow to the nozzle of the hydrogen torch to change a thermal output level of the flame with reference to a change in distance between the nozzle of the hydrogen torch and the print surface during the operating of the actuator.

  • Patent number: 9944094
    Abstract: A media transport system includes a drum with a plurality of rows of holes, a vacuum plenum, and a shutter. The vacuum plenum is positioned within the drum at a position opposite a printhead and the shutter is configured for movement in a cross-process direction. Each row of holes in the drum includes at least one inter-copy gap. The shutter includes a solid member having at least one aperture in it. The shutter is moved to a position so the aperture is aligned with a row of holes and the solid portion of the shutter prevents a flow of air through the vacuum plenum from the holes in other rows of holes not aligned with the aperture in the shutter and the inter-copy gaps in the row of holes aligned with the aperture selectively prevents air flow to the vacuum plenum.
