Abstract: An aqueous ink printer includes a dryer that enables coated substrates to be printed with aqueous ink images. The dryer is configured to receive substrates from a first substrate transport and to hold a plurality of the substrates for a predetermined period of time to dry the aqueous ink images on the substrates before independently releasing each substrate in the plurality of substrates to a second substrate transport.

Abstract: A direct-to-object printer includes an object rotating subsystem. The object rotating subsystem includes an actuator with an output shaft, a holder mounted to the output shaft, the holder being configured to grip a portion of the object, and a controller operatively connected to the actuator. The controller is configured to operate the actuator to rotate the holder and the object gripped by the holder to enable at least one of the printheads in a printer to print a portion of a circumference of the object that is longer than a width of the at least one printhead.

Abstract: What is disclosed is an object holder for retaining an object in a direct-to-object print system and a direct-to-object print system configured to use various embodiments of the object holder of the present invention. In one embodiment, the object holder comprises a shuttle mount configured to slideably traverse a support member positioned parallel to a plane formed by the printhead. At least one collapsible membrane is attached to the shuttle mount. The membrane forms an airtight sack filled with granules. The membrane collapses at least partially around an object when a volume of air is withdrawn from the membrane by a vacuum pump. The vacuum pump withdrawing a volume of air from the membrane causes the membrane to collapse and tightly pack the granules inside the membrane. The vacuum-packed granules cause the membrane to conform to the shape of the object thereby securing the object to the shuttle mount.

Abstract: An inkjet printer applies a layer of a hydrophilic composition, which includes a liquid carrier and an absorption agent, to an image receiving surface of an indirect image receiving member. A dryer in the printer removes a portion of the liquid carrier from the layer of hydrophilic composition to form a dried layer of an absorption agent on the image receiving surface and an aqueous ink image is formed on the dried layer. The aqueous ink image and at least a portion of the dried layer are transferred to a surface of a print medium as the aqueous ink image and print medium move through a transfix nip formed between the indirect image receiving member and a transfix member.

Abstract: An inkjet printer prints on a first side of a media sheet less than all of the color separations in an image, generates a first set of image data of the printed color separations to identify image features, returns the partially printed media sheet to a position that precedes the print zone in the printer, generates a second set of image data of the partially printed media sheet before it reenters the print zone to identify the image features, compares the positions of the image features in the first set of image data to the positions of the image features in the second set of image data to register one or more color separations remaining to be printed with the color separations printed on the first side of the media sheet, and prints the remaining registered color separations on the first side of the partially printed media sheet.

Abstract: Devices include first and second frame elements having mounting points connectable to opposite ends (e.g., first end, second end) of the touchscreen. First and second rollers are connected, respectively, to the first and second frame elements. A web of transparent material is supported by and between the first and second rollers. Further, an ultraviolet light device is connected to the second frame element and is positioned to expose the web of transparent material to ultraviolet radiation to disinfect the transparent material between users.

Abstract: A method of operating a printer identifies image areas in ink image content data that are likely to affected by airflow disturbances to produce ink blur within an ink image. Inkjets farthest from these areas are selected to eject ink drops into these areas to form portions of an ink image. The image areas identified as being likely to produce ink blur are the leading edge, trailing edge, and side edge of the ink image content data. The ink drops ejected by these selected inkjets and their satellites are less likely to be affected adversely by the airflow disturbances.

Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with two solid metal moving mechanisms that are independently operated to move two different metals into the receptacle of a vessel in a melted metal drop ejecting apparatus. The ejector is operated to form object features with melted metal drops of one of the two different metals and to form support features with melted metal drops of the other of the two different metals. The thermal expansion coefficients of the two metals are sufficiently different that the support features easily separate from the object features after the object and support features cool.

Abstract: A printing system comprises a printhead to eject a print fluid to a deposition region. A movable support surface, such as a belt, is used to transport print media through the deposition region, with the print media being held against the movable support surface by vacuum suction through holes in the movable support surface. A media registration device loads print media onto the movable support surface and registers the print media to a location of the movable support surface. The movable support surface comprises no-suction-regions in which the vacuum suction through the movable support surface is prevented. The no-suction regions extend across the width of the movable support surface in a cross-process direction and are arranged at predetermined intervals along the process direction. The control system causes the media registration device to register each of the print media relative to a respective one of the no-suction-regions.
