摘要:
Approaches to remove bubbles from ink in an ink jet printer are described. Bubble removal may be implemented using one or more separator elements configured to separate bubbles of a vapor from ink. Each separator element includes wicking features having dimensions sufficient to allow capillary movement of the ink in the wicking features and to substantially exclude the bubbles from the wicking features. One or more inlets allow passage of the ink that includes the bubbles into the separator element. At least one vapor outlet allows vapor that has been separated from the ink to exit from the separator element. The ink exits from the separator element thought one or more ink outlets.

An apparatus controls dissipation of heat from melted ink within a component storing melted ink within a solid ink imaging device. The apparatus includes a housing, a passage within the housing that is configured to store melted ink, and a temperature control connector mechanically coupled to the housing and passage, the temperature control connector being configured to mitigate void formation in melted ink as the melted ink cools in the passage.

A high throughput parcel unloading system includes a robotic arm arrangement, including a cluster of robotic arms having grouping mechanisms. A conveyor system is also provided onto which parcels are placed by the robotic arm system. An image recognition system determines the position and arrangement of parcels within a container, and a control system is configured to receive image information from the image recognition system and control operation of the robotic arm system and conveyor system.

A print head assembly for an ink jet printer includes an ink flow path configured to allow passage of a phase-change ink. A pressure unit is fluidically coupled to the ink flow path to apply a pressure to the ink. The applied pressure is controlled by a control unit during a time that the ink in the ink flow path is undergoing a phase change. During the phase change, a portion of the ink in a first region of the ink flow path is in liquid phase and another portion of the ink in another region of the ink flow path is in solid phase. A constant or variable pressure can be applied at least to the liquid phase portion of the ink during a phase transition from a liquid phase to a solid phase or from a solid phase to a liquid phase.

A printed mask derived from a composition comprised of at least one compound including at least one alkaline-hydrolyzable group, and at least one compound including at least one ethylene oxide group. The printed mask is removable using an alkaline solution in about 30 seconds or less.
摘要:
Wafer-based solar cells are efficiently produced by extruding a dopant bearing material (dopant ink) onto one or more predetermined surface areas of a semiconductor wafer, and then thermally treating the wafer to cause diffusion of dopant from the dopant ink into the wafer to form corresponding doped regions. A multi-plenum extrusion head is used to simultaneously extrude interdigitated dopant ink structures having two different dopant types (e.g., n-type dopant ink and p-type dopant ink) in a self-registered arrangement on the wafer surface. The extrusion head is fabricated by laminating multiple sheets of micro-machined silicon that define one or more ink flow passages. A non-doping or lightly doped ink is co-extruded with heavy doped ink to serve as a spacer or barrier, and optionally forms a cap that entirely covers the heavy doped ink. A hybrid thermal treatment utilizes a gaseous dopant to simultaneously dope exposed portions of the wafer.
摘要:
A printing system and method combine conventional print and reusable print media functionality in a shared stand-alone system to allow a user flexibility in deciding whether to print a temporary document or an archival permanent document. The system integrates and shares functionality to reduce manufacturing and operating costs, as well as to reduce the device's footprint. Commonality may include a common printhead shuttling mechanism (traversing carriage) and portions of the mechanism for moving paper. Pre-conditioning and printzone conditioning stations may also be shared to achieve precondition heating and/or erasing of media sheets prior to printing and maintaining of an elevated temperature during printing. In embodiments, separate feed trays are provided for each media sheet type.

A method and apparatus for automatically adjusting nip width based on a scanned nip print image on ultraviolet (UV)-sensitive media in an image production device is disclosed. The method may include receiving a signal to generate a nip print, automatically inserting a sheet of UV-sensitive media into a fuser nip in the image production device, pausing the sheet of UV-sensitive media in the fuser nip for a predetermined time period, illuminating the UV-sensitive media with ultraviolet light to generate a nip print, scanning the generated nip print, determining if a nip width adjustment is required based on the scanned nip print, and if it is determined that a nip width adjustment is required based on the scanned nip print, adjusting the nip width using a nip width adjustment device.
摘要:
A system and a method print one or more images to one or more reimageable documents, wherein the one or more representative of at least a portion of a digital file. The method includes a connecting a portable printer to a computing device. Moreover, the method includes emitting ultraviolet light from a light source, wherein an imaging layer of the reimageable document is imagable by ultraviolet light, wherein ultraviolet light forms a color contrast on the imaging layer that defines an image representative of at least a portion of the digital file.
