摘要： A method of operating a printer distributes inkjet operations from frequently used inkjets to lesser used inkjets. The redistribution of the inkjet operations helps reduce the number of inkjets exhibiting cross-process direction error so printhead maintenance operations, such as purging, occur less frequently.

摘要： A metal object produced by a three-dimensional (3D) metal object manufacturing apparatus is subjected to a high temperature heat treatment to improve bonding of the object layers, especially in the vertical or Z-axis direction. A supporting structure is formed around the metal object to retain the shape and features of the object during the high temperature heat treatment. The supporting structure is formed in a manner that is sufficient to retain the shape of the metal object during the heat treatment but is easily removed once the heat treatment is finished.

摘要： Nozzles for additive manufacturing and methods for improving wettability of the nozzles are disclosed. The nozzle may include a body having an inner surface and an outer surface. The inner surface may define an inner volume of the nozzle, and may have a water contact angle of greater than 1° and less than about 90°. The method may include subjecting the nozzle to a surface treatment. The surface treatment may include plasma treating a surface of the nozzle such that free radicals, polar functional groups, or a combination thereof are formed at the surface of the nozzle.

摘要： An adhesive sign suited to use in retail applications includes a substrate layer. An adhesive layer is disposed on the substrate layer. The adhesive layer defines an exposed region for attachment to an associated structure. The adhesive layer is derived from a photo-curable inkjet composition. An ink layer is disposed on the substrate layer. The ink layer includes an image. The ink layer is derived from a photo-curable inkjet composition. The adhesive layer and ink layer can be formed in the same inkjet printing process and cured in a common photo-curing station. A stack of the adhesive signs can be assembled without interleaving a release liner between each pair of signs.

摘要： A dryer for use in an aqueous ink printer adequately dries coated substrates printed with aqueous ink images before discharge of the substrates. The dryer has a housing, a plurality of laser diodes, a current source, a variable electrical resistance network having a plurality of resistors, and a controller. The controller is configured to identify a plurality of ink coverage densities for a plurality of areas in an ink image that passes through the dryer, select and vary an electrical resistance of one or more of the resistors in the variable electrical resistance network using the identified ink coverage densities, and operate the plurality of resistors in the variable electrical resistance network to connect the laser diodes in the dryer selectively to the current source through the plurality of resistors using the identified ink coverage densities and a speed of the substrate through the dryer.

摘要： A self-advancing cleaner and a method of operating the self-advancing cleaner. In an embodiment, a rotatable member can engage a transport belt, wherein the rotatable member includes a cleaning surface comprising a surface sufficiently rough to collect and take away ink debris from the transport belt. During a cleaning operation the cleaning surface remains stationary while the transport belt moves in a sliding relative motion with respect to the cleaning surface, which allows the ink debris to be collected on the cleaning surface. Once an ink contamination level associated with the ink debris attains a threshold and a set friction exceeds the threshold, the self-advancing cleaner advances.

摘要： A cleaning subsystem for a variable data lithography system includes a cleaning roller train having a cleaning member in physical contact with an imaging member such that residual ink remaining on the imaging member, such as following transfer of an inked latent image from the imaging member to a substrate, adheres to the cleaning member through cohesion and is thereby removed from the imaging member. The cleaning roller train uses the ink-splitting mechanics to remove, transport and collect the ink waste. The key cleaning roller train is a thin but uniform layer of ink on the cleaning member that contacts the imaging member causing removal on the residual ink through cohesion.

摘要： An aqueous ink printer includes a dryer that enables coated substrates printed with aqueous ink images to be adequately dried before discharge of the substrates. The dryer has a housing, a plurality of laser diodes, and a controller configured to operate the laser diodes with reference to ink coverage densities in an ink image and a speed of a media transport moving the substrate bearing the ink image as the substrate passes the plurality of diodes. The controller varies the intensity of the radiation emitted by the laser diodes to correspond with the ink coverage density opposite each laser diode as the ink image passes through the dryer.
