  • Patent number: 11221579
    Abstract: A printer for producing a print media moving in a process direction including a print engine, a fuser, a full width array and a duplexing path. The print engine is operatively arranged to receive the print media and to apply a first dry marking material to a first surface of the print media. The fuser is arranged subsequently to the print engine in the process direction and is operatively arranged to receive the print media with the first dry marking material applied to the first surface of the print media and to fix the first dry marking material on the first surface using at least one of heat and pressure. The full width array is arranged subsequently to the fuser and is operatively arranged to obtain a first image of the first surface of the print media, the first image being used to quantify a flatness of the print media and/or image quality of the first image. The duplexing path is arranged subsequently to the full width array.

  • Publication number: 20210409021
    Abstract: An ultra-high resolution capacitive sensor affixed above an imaging member surface measures the thickness of fountain solution on the imaging member surface in real-time during a printing operation. The sensor is considered ultra-high resolution with a resolution high enough to detect nanometer scale thicknesses. The capacitive sensor would initially be zeroed to the imaging member surface. As fluid is added, the capacitive sensor detects the increase and can measure and communicate with the image forming device to adjust fountain solution flow rate to the imaging member surface and correct for any anomalies in thickness. This fountain solution monitoring system may be fully automated. The capacitive sensor may have a resolution (e.g., as low as about 1 nm resolution) of about 0.001% of the distance/gap that the capacitive sensor is mounted away from the imaging member surface.

  • Patent number: 11198580
    Abstract: An apparatus is disclosed. For example, the apparatus includes a paper feed to feed print media a single sheet at a time, a plurality of rotating discs, wherein each one of the plurality of rotating discs comprises an elastomer ring to secure a leading edge of the single sheet against a registration wall and initiate a flipping process, a curved baffle positioned above the plurality of rotating discs and the single sheet, an air duct located above the plurality of rotating discs and the single sheet to force an air flow towards the curved baffle, wherein the air flow follows a shape of the curved baffle to create a low pressure zone above the single sheet to keep a trailing edge of the single sheet levitated during completion of the flipping process, and a movable platform to hold a stack of the print media.

  • Patent number: 11117774
    Abstract: A system for controlling curl in sheets passing beneath a camera includes applying a thin layer of high velocity air to a curved baffle positioned beneath the camera. The high velocity air layer, which will have a tendency to follow the curved baffle (Coanda effect), will divert sheets (Bernoulli effect) towards the curved baffle. By positioning the curved baffle along the media paper path and by applying a uniform air stream to it, a lower pressure area will be created. This will flatten the trajectory of the sheets and thereby remove curl before the sheets pass the camera.

  • Patent number: 11046544
    Abstract: An apparatus for controlling cross curl in corners of sheets between in-line transports includes a curved baffle placed between the two transports. A thin layer of high velocity air is applied to the curved baffle only at lead edge corner regions of the sheets. The high velocity air layer, which will have a tendency to follow the curved baffle (Coanda effect), will divert corners of the sheets (Bernoulli effect) towards the curved baffle. By positioning a curved baffle between the two transports and by applying a uniform air stream to it, a lower pressure area will be created. This will flatten the corners of the sheets and ensure passage between downstream baffles and acquisition by a downstream transport.

  • Publication number: 20210171307
    Abstract: Printing apparatuses include (among other components) a photoreceptor (that is adapted to contact and transfer marking material to a printing side of sheets of media), a transport belt adjacent the photoreceptor, a baffle, and an air outlet. The sheets of media are moved by the photoreceptor across a gap to the transport belt in a “processing direction.” The baffle is adjacent the back side of the sheets of media (the side that is opposite to the printing side of the sheets of media). The air outlet is also positioned adjacent the back side of the sheets of media, and the air outlet is adapted to direct a stream of air along the baffle and between the baffle and the back side of the sheets of media to lift the sheets of media off the photoreceptor without damaging the sheets of media or disturbing the unfused marking material thereon.

  • Patent number: 10773917
    Abstract: A sheet profile input area is displayed on a user interface. The user interface can be in communication with a processor and a decurler device. The decurler device receives sheets output by any form of sheet output device that may add curl to the sheets. User input that corresponds to the curl of the sheets is received into the sheet profile input area. The decurler device is controlled to remove the curl of the sheets based on the user input by causing the decurler device to contact the sheets after the sheets are output from the sheet output device.

  • Patent number: 10696051
    Abstract: Devices and processes include/use an inkjet printhead, a sheet transport positioned to move sheets of media past the inkjet printhead, a sheet registration device positioned to align the sheets of media, and a controller electrically connected to the inkjet printhead and the sheet registration device. The controller is adapted to periodically control the sheet registration device to align a first sacrificial sheet with a first edge of the sheet transport and align a second sacrificial sheet with a second edge of the sheet transport and that is opposite the first edge. The controller is adapted to control the inkjet printhead to eject ink from a first set of nozzles to the first sacrificial sheet and eject ink from a second set of nozzles to the second sacrificial sheet. The first set of nozzles contains different nozzles from the second set of nozzles.

  • Patent number: 10682843
    Abstract: A direct-to-object printer includes an object indexing subsystem. The object indexing subsystem includes an indexer actuator that operates a rotating indexer to rotate a collar in which an object is mounted. The amount of collar rotation enables the object held by the collar to be turned a predetermined angular amount so operation of the indexing subsystem between passes by a plurality of printheads enables different portions of a curved object surface to be printed during different passes.

  • Patent number: 10589950
    Abstract: A gravity-assisted registration system suited to use in a printing device includes a transport member with a surface on which an associated sheet is translated in a process direction. The surface defines an angle with respect to horizontal in a cross-process direction. A registration wall, adjacent a lower end of the surface, defines a registration edge for registering the sheet. A drive mechanism drives at least one rotation mechanism, for translating sheet in the process direction, each rotation mechanism including at least one drive member with an axis of rotation parallel to the surface in the cross-process direction, Each drive member includes a sliding mechanism, at a periphery of the drive member, enabling the sheet to slide, under gravity, on the surface, toward the registration wall into an alignment position, in contact with the registration wall.

  • Patent number: 10546243
    Abstract: This disclosure relates to a method for estimating a particle size distribution (PSD) and a morphology for a set of particles. A computer system receives a plurality of chord length distributions (CLDs) of different types for a set of particles. The computer system then estimates a morphology for the set of particles based on the plurality of received CLDs. The computer system also identifies a plurality of descriptors of the plurality of CLDs for the set of particles based on the plurality of received CLDs. The computer system then estimates metrics for the PSD for the set of particles based on the plurality of identified CLD descriptors. Based on the estimated PSD metrics for the set of particles, the computer system generates an estimate of the PSD for the set of particles. Finally, the computer system outputs the estimated morphology and the estimated PSD for the set of particles.
