Abstract: A cap is positioned to contact a printhead when the printhead is not ejecting liquid ink. The cap and the printhead create a sealed space adjacent printhead nozzles when contacting each other. A flexible blade is positioned to contact the printhead when the printhead is not in contact with the cap. The flexible blade is adapted to fold over to spread a liquid solution on the nozzles in a first direction, and the flexible blade is adapted to remove excess amounts of the liquid solution from the nozzles in a second direction. A humidifier is connected to the cap and adapted to supply a moisture form of the liquid solution to the sealed space. A moisture sensor is connected to the cap. The humidifier is adapted to vary supply of the moisture to the sealed space based on the amount of moisture detected by the moisture sensor.

Abstract: A three-dimensional (3-D) printer includes build and support material development stations positioned to transfer layers of build and support materials to an intermediate transfer surface. A platen having a flat surface is positioned to contact the intermediate transfer surface. The intermediate transfer surface transfers a layer of the build and support materials to the flat surface of the platen as the platen contacts one of the layers on the intermediate transfer surface. A dispenser is positioned to deposit a leveling material on the layer on the platen, and a mechanical planer is positioned to contact and level the leveling material on the layer on the platen to make the top of the leveling material parallel to the flat surface of the platen.

Abstract: A system dynamically balances a rotating body. The system includes a support that holds the body as it rotates. At least one sensor generates signals indicative of a balance of the body as it rotates and a controller identifies a position on the body where material can be placed to balance the body. The controller operates at least one actuator to move a plurality of ejectors opposite the identified position where the controller operates at least one ejector in the plurality of ejectors to eject material onto the identified position. The system can operate iteratively until the body is balanced within a predetermined range.

Abstract: A three-dimensional (3-D) printer includes build and support material development stations positioned to transfer layers of build and support materials to an intermediate transfer surface. The intermediate transfer surface transfers a layer of the build and support materials to a platen each time the platen contacts the intermediate transfer surface. A sensor detects the thickness of the layer on the platen, and a mechanical planer is positioned to contact and level the layer on the platen as the platen moves past the mechanical planer. Additionally, a feedback loop is electrically connected to the sensor and the mechanical planer. The mechanical planer adjusts the amount of the build material and the support material removed from the layer based on the thickness of the layer on the platen, as determined by the sensor.

Abstract: 3-D printers include an intermediate transfer surface that transfers a layer of material to a platen each time the platen contacts the intermediate transfer surface to successively form a freestanding stack of layers of the material on the platen. A sensor detects the thickness of the layer on the platen after a fusing station fuses the layer. A feedback loop is electrically connected to the sensor and a development station (that includes a photoreceptor, a charging station providing a static charge to the photoreceptor, a laser device exposing the photoreceptor, and a development device supplying the material to the photoreceptor). The development station adjusts the transfer bias of the development device, based on a layer thickness measurement from the sensor through the feedback loop, to control the thickness of subsequent ones of the layers transferred from the intermediate transfer surface to the freestanding stack on the platen.

Abstract: A 3-D printer includes build and support material development stations that electrostatically transfer build material and support material to an ITB. The ITB transfers a layer of build and support material to a platen each time the platen contacts one of the layers on the ITB, to successively form a freestanding stack of the layers on the platen. A sensor is positioned to generate a topographic measurement of the layer on the platen, and an aerosol applicator is positioned to propel build and support material on to the layer on the platen. The aerosol applicator controls the build and support material being propelled, based on the topographic measurement from the sensor through a feedback loop, to adjust the amount and location of the build material and the support material propelled on to the layer, and thereby control the flatness of surface topology of the layers in the freestanding stack on the platen.

Abstract: A system and method are provided for implementing a unique electrophotographic layered manufacturing scheme for creating higher fidelity electrophotographic composite laminate layers using tri-level electrophotography or electrostatic imaging scheme as a process for rendering individual laminate layers to be built up to form and/or manufacture three-dimensional objects, parts and components as 3D objects. A multi-stage 3D object forming scheme is described involving steps of multi-component laminate forming in a particularized electrophotographic layer forming process. This process renders a part component and a support component precisely next to one another with a single exposure by an exposing device to form a latent image of variable discharge voltages. Multiple toner product sources are used to dispose part component toner and support component toner in the forming of the multi-component laminate layer.

Abstract: A printer includes a surface preparatory material remover. The remover is configured with a pad mounted to a roller to engage selectively the surface preparatory material on a surface of a rotating member to remove a portion of the surface preparatory material outside of an area where an ink image is formed to reduce the adhesion of media to the rotating member surface as the media exits a nip in which the ink image is transferred to the media.
