Abstract: Alignment apparatuses include a frame and contact elements connected to the frame. The contact elements contact items that are to be transported in a processing direction relative to the frame. The contact elements are in permeant fixed positions relative to the frame, and do not move relative to the frame. Adjustable mounts are connected to the frame and move the frame in the processing direction and in a perpendicular cross-processing direction. A controller is electrically connected to the adjustable mounts, and the controller is adapted to control the adjustable mounts to simultaneously move the frame and all the contact elements in the cross-processing direction and the processing direction while rotating the frame. Methods laterally shift imaging on sheets that have had rotational correction performed by such alignment apparatuses.

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 heated evaporator is connected to the cap and is adapted to evaporate an ink-compatible liquid to form a water and/or solvent vapor and supply the water and/or solvent vapor to the sealed space to protect the liquid ink in the nozzles. An insulator thermally insulates the heated evaporator from the printhead. This prevents the ink in the nozzles from drying and prevents the nozzles from clogging.

Abstract: An inkjet printer is configured with capping stations for storing printheads in the printer during periods of printer inactivity so the viscosity of the ink in the nozzles of the inkjets of the printheads does not increase significantly. Each capping station has a printhead receptacle that encloses a volume, a planar member configured to move between a first position at which the planar member is located within the printhead receptacle and a second position at which the planar member is external of the printhead receptacle, a first actuator operatively connected to the planar member, the first actuator being configured to move the planar member from the first position to the second position, and a controller configured to operate the first actuator to move the planar member from the first position to the second position to mate the planar member with a face of a printhead.

Abstract: Ink stabilizing material is applied to rotatable panels within a cap of an inkjet cartridge resting structure. The rotatable panels then rotate to contact an inkjet printhead when the printhead contacts the cap. Continuous periodic flushing of the printhead is performed while the rotatable panels are contacting the printhead by periodically and repeatedly alternating between ejecting a mixture of the ink stabilizing material and ink from the nozzles, and drawing the mixture of the ink stabilizing material and the ink back into the nozzles.

Abstract: A system for printing on a multi-dimensional object includes a plurality of print heads, a mounting structure configured to receive an integrated object packaging and holder for an object and to movably mount on a support member, an actuator configured to move the mounting structure along the support member, and a processing device. The system also includes a non-transitory, computer-readable memory containing programming instructions that are configured to cause the processing device to control a movement of the mounting structure relative to the plurality of print heads, and operate the plurality of print heads to eject marking material onto an object mounted on the mounting structure.

Abstract: A registration system for a printing device and a method for controlling the same are disclosed. For example, the registration system includes at least one sensor to detect a position of a print media, at least one laterally adjustable nip, wherein the laterally adjustable nip moves along an inboard direction and an outboard direction, a motor coupled to the at least one laterally adjustable nip to move the at least one laterally adjustable nip a desired amount of movement based on the position of the print media and a width of the print media, and a processor communicatively coupled to the at least one sensor and the motor to calculate a desired amount of movement based on the position of the print media and control the motor to move the at least one laterally adjustable nip by the desired amount of movement.

Abstract: Layers of build and support material on an intermediate transfer surface are exposed to a solvent using a solvent application station to make the build material tacky, without affecting the support material. Then, the intermediate transfer surface moves past a transfuse station (the transfuse station is positioned to receive the layers after exposure to the solvent) and a platen moves relative to the intermediate transfer surface to contact the platen to one of the layers on the intermediate transfer surface. The intermediate transfer surface transfers a layer of the build material and the support material to the platen each time the platen contacts the layers on the intermediate transfer surface at the transfuse station to successively form a freestanding stack of the layers of build and support material on the platen.

Abstract: Printing devices include a media supply storing print media, a luminescent belt positioned adjacent the media supply in a location to move sheets of the print media from the media supply, a print engine positioned adjacent the luminescent belt in a location to receive the sheets from the luminescent belt, an optical sensor positioned adjacent the belt in a location to receive belt-emitted light from the luminescent belt, and a processor electrically connected to the optical sensor. The processor receives the image from the optical sensor and identifies locations of the sheets on the belt based on where the sheets block the belt-emitted light from the luminescent belt.

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.
