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: The nozzles of a MHD liquid metal ejector/printhead can be clogged by contaminants in the liquid metal. Typically, these contaminants are in the form of small particles of aggregates of particles, such as metal oxides, that are insoluble in the liquid metal. Possible cleaning methods include mechanically removing the clogging material, such as by using a physical device to dislodge the clogging material and remove it; chemically removing the clogging material, such as by using selected chemicals/flux to chemically react with the clogging material; using ultrasound to break/remove the clogging material; and providing reversed and/or oscillating flow of material through the nozzle.

Abstract: A printing module and a method for controlling the same are disclosed. For example, the printing module includes a plurality of printheads, a transport belt located below the plurality of printheads to transport print media below the plurality of printheads, wherein the transport belt comprises a plurality of vacuum openings, and a positive pressure plenum system, wherein the positive pressure plenum system provides a positive air flow to create an air interface between a top surface of the positive pressure plenum system and a bottom surface of the transport belt, wherein the positive pressure plenum system provides a negative air flow to create a vacuum through the plurality of vacuum openings of the transport belt to hold the print media against the transport belt.

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. An evaporator is connected to the cap and is adapted to control evaporation a water-incompatible or solvent-incompatible liquid into the sealed space to condense an ink-blocking film on the surface of the liquid ink in the nozzles to protect the liquid ink in the nozzles. 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: A printer is configured with at least two printheads that are separated from one another in a cross-process direction by an integral multiple of printhead widths. This configuration enables parallel swaths of material to be ejected and then movement of the printheads in the cross-process direction by a distance corresponding to one or more integral numbers of the printhead width enables the area between the swaths to be completed and the area outside of the original swaths printed.

Abstract: An aqueous ink printer includes an anti-curl fluid applicator that applies anti-curl fluid to a side of a substrate that is opposite a side that bears or will bear an ink image. The anti-curl fluid applicator includes a switching network that is configured to independently and selectively bias segments of a pressure member electrically. The segments are arranged along a longitudinal axis of the pressure member. The pressure member forms a nip with a anilox roller partially immersed in a reservoir of anti-curl fluid. As the switching network is operationed to selectively and independently bias the segments electrically using data corresponding to the ink image, anti-curl fluid migrates from the anilox roller onto the substrate in areas opposite the electrically biased segments.

Abstract: An aqueous ink printer includes a moisture applicator that applies moisture to a side of a substrate that is opposite a side that bears or will bear an ink image. The moisture applicator includes a switching network that is configured to independently and selectively bias the tile segments electrically. The tile segments contiguously cover a surface of the roller. As the switching network is operated to electrically bias the tile segments using data corresponding to the ink image, they transition from being hydrophobic to hydrophilic so the electrically-biased hydrophilic tile segments attract moisture from water in a trough or from water vapor produced by an ultrasonic transducer in the trough. The moisture is carried by the electrically-biased tile segments to the substrate at areas where the amount of ink in a portion of the substrate on the other side of the substrate exceeds a predetermined ink coverage threshold.

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 cap is positioned to contact a printhead when the printhead is not ejecting liquid ink onto print media. A dispenser dispenses an ink stabilizing material into the cap. A blocking structure is positioned in the cap to contact vent openings of the inkjet printhead when the inkjet printhead is in the cap and is in a location to submerge the nozzles in the ink stabilizing material in the cap. An ink control device draws the ink stabilizing material into nozzles of the inkjet printhead when the vent openings are blocked by the blocking structure. The ink control device subsequently draws the ink stabilizing material into the vent openings when the vent openings are separated from the blocking structure.

For example, the indicator tag includes a three-dimensional mesh comprising a plurality of pores, wherein the three-dimensional mesh is printed with a water soluble and ultra-violet (UV) light curable ink, a container enclosing the three-dimensional mesh, a membrane coupled to the three-dimensional mesh, and a dye dispensed on top of the membrane, wherein the three-dimensional mesh interacts with the dye when in contact with the dye to provide an indication.

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.
