Abstract: An optical light reflectance measurement system above an imaging member surface measures fountain solution surface light reflectance interference on reflective substrate portions of the imaging member surface in real-time during a printing operation. The measured light reflectance interference corresponds to a thickness of the fountain solution layer and may be used in a feedback loop to actively control fountain solution layer thickness by adjusting the volumetric feed rate of fountain solution added onto the imaging member surface during a printing operation to reach a desired uniform thickness for the printing. This fountain solution monitoring system may be fully automated.

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: A three-dimensional object printing system improves the collection of waste materials during object printing. The printing system includes an ejector head configured to eject material, a platform configured to move in a process direction to a position opposite the ejector head to enable the ejector head to eject material onto the platform, and first and second planarizers configured to remove a first portion and a second portion, respectively, of the material ejected onto the platform. The printing system further includes a first housing defining a first chamber in which at least one of the first planarizer and the second planarizer is positioned, and a first vacuum source connected to the first housing, the first vacuum source being configured to produce a first vacuum in the first chamber to pull material removed by the at least one of the first planarizer and the second planarizer from the first chamber.

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 alignment features.

Abstract: A printing system includes a first member and a second member. The second member is positioned parallel to the first member. The system further includes a first extensible member and a second extensible member. The system further includes a first gripper and a second gripper. One end of the first extensible member is mounted to the first member and the other end of the first extensible member is mounted to the first gripper. One end of the second extensible member is mounted to the second member and the other end is mounted to the second gripper. A controller operates a first actuator operatively connected to the first and second extensible members.
