Abstract: An inkjet printhead assembly includes a controller operatively connected to an actuator so the controller can operate the actuator to tilt a carrier plate in which a plurality of printheads are mounted after a purge of the printheads has been performed. The tilt assists gravity in directing the purged ink to a wiper that is moved by another actuator operated by the controller to wipe the faceplates of one or more printhead faceplates in the carrier plate. After the wiper is returned to its home position, the carrier plate is returned to its level position and the printhead assembly is returned to its operational position for printing.

Abstract: An apparatus includes, among other components, a frame adapted to be connected to the exterior surface of a device that has a touchscreen. A retractable cover is operatively connected to the frame. The size of the retractable cover is equal to at least the size of the touchscreen, and the retractable cover is positioned to extend so as to cover the touchscreen. At least one ultraviolet light is also operatively connected to the frame. The ultraviolet light is positioned to direct ultraviolet lighting toward the touchscreen when the retractable cover extends to cover the touchscreen.

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: 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: 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: An imaging system includes a substrate cooler that reduces the temperature of substrates bearing dried ink images. The substrate cooler has a plurality of rollers, at least one actuator operatively connected to the plurality of rollers, and a controller operatively connected to the least one actuator. The controller is configured to operate the at least one actuator to move the rollers relative to one another to vary the length of the path along which the substrates move through the substrate cooler.

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: An inkjet printhead prints test patches of magnetic ink having magnetic particles using different ink droplet sizes on print media. A sensor scans the test patches to determine test patch densities. A processor determines a table-based density that produces a user-selected magnetic strength by applying the selected magnetic strength to a density and magnetic strength relationship table. The processor identifies a matching test patch as one of the test patches having a density that most closely matches the table-based density, identifies a selected droplet size as the ink droplet size used to print the matching test patch, and controls the printhead to produce magnetic ink droplets of the selected droplet size when printing a print job for the selected magnetic strength.

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.
