Abstract: A direct-to-object printer includes an object indexing subsystem. The object indexing subsystem includes an indexer actuator that operates a rotating indexer to rotate a collar in which an object is mounted. The amount of collar rotation enables the object held by the collar to be turned a predetermined angular amount so operation of the indexing subsystem between passes by a plurality of printheads enables different portions of a curved object surface to be printed during different passes.

Abstract: A method, non-transitory computer readable medium, and apparatus for adjusting and moving a user interface for single handed use on an endpoint device are disclosed. For example, the method determines a thumb span of a hand of a user on a touch screen display of the endpoint device, detects via one or more sensors on the endpoint device that the user is holding the endpoint device with a single hand, adjusting a size of the user interface to be within dimensions of the thumb span in response to the detecting and moves the user interface in a direction towards the single hand in response to the detecting.

Abstract: An ultra-high resolution capacitive sensor affixed above an imaging member surface measures the thickness of fountain solution on the imaging member surface in real-time during a printing operation. The sensor is considered ultra-high resolution with a resolution high enough to detect nanometer scale thicknesses. The capacitive sensor would initially be zeroed to the imaging member surface. As fluid is added, the capacitive sensor detects the increase and can measure and communicate with the image forming device to adjust fountain solution flow rate to the imaging member surface and correct for any anomalies in thickness. This fountain solution monitoring system may be fully automated. The capacitive sensor may have a resolution (e.g., as low as about 1 nm resolution) of about 0.001% of the distance/gap that the capacitive sensor is mounted away from the imaging member surface.

Abstract: An apparatus for controlling curl in sheets between two transports includes a curved baffle placed between the two transports. A thin layer of high velocity air is applied to the curved baffle. The high velocity air layer, which will have a tendency to follow the curved baffle (Coanda effect), will divert sheets (Bernoulli effect) towards the curved baffle. By positioning the curved baffle between the two transports and by applying a uniform air stream to it, a lower pressure area will be created. This will flatten the trajectory of the sheets and ensure acquisition by the downstream transport.

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. The object holder comprises a shuttle mount configured to slideably traverse a support member positioned parallel to a plane formed by at least one printhead of a direct-to-object print system. An expandable bladder attached to either the shuttle mount or a restraint. The bladder is inserted in a cavity of an object to be printed. A pump then fills the bladder with either a gas or a liquid to cause the bladder to expand. The expanded bladder in the object's cavity enables a surface of the object to be printed. In one embodiment, the filled bladder substantially conforms to a shape of a human foot, and the object being printed is footwear.

Abstract: 3-D printing system include development stations positioned to electrostatically transfer build and support materials to an intermediate transfer surface, a transfer station adjacent the intermediate transfer surface, guides adjacent the transfer station, and platens moving on the guides. The guides are shaped to direct the platens to repeatedly pass the transfer station and come in contact with the intermediate transfer surface at the transfer station. The intermediate transfer surface transfers a layer of the build and support materials to the platens each time the platens contact the intermediate transfer surface at the transfer station to successively form layers of the build and support materials on the platens. The platens and the intermediate transfer surface include rack and pinion structures that temporarily join at the transfer station, as the platens pass the transfer station, to align the platens with the intermediate transfer surface as the platens contact the intermediate transfer surface.

Abstract: A printer detects inoperative inkjets during printing of three dimensional objects. The printer includes a substrate onto which a printhead ejects building and support material in a test pattern. An ultrasonic sensor scans the substrate on the unprinted side and measures thicknesses at a plurality of locations on the substrate. The thickness measurements are used to identify inoperative inkjets in the printhead and the printing of an object can be suspended to take remedial action with regard to the printhead before formation of the object is completed.
