Assignee:

Xerox Corporation - Norwalk CT

International Classification:

B41J 2/01

US Classification:

347103, 347 88, 347 99

Abstract:

A method and apparatus for metering release agent on an imaging member includes applying a release agent to a rotating imaging member at an application location and then controlling a thickness of the release agent on the imaging member with a rotating metering roll. In at least one embodiment, the method for metering a release agent includes rotating the metering roll as a counter-roll to an imaging drum such that the metering roll moves in an opposite direction from the imaging drum at a nip between the metering roll and the imaging drum. The metering roll may include an elastomer provided over the substantial portion of its outer surface which contacts the imaging drum. The metering roll may also be forcibly biased against the imaging drum. At least one wiper blade may be provided in contact with the metering roll to wipe excess release agent from the metering roll.

International Classification:

B42D 15/00

US Classification:

283102, 283100, 283901, 283903

Abstract:

A scratch-off document may include a substrate bearing a toner image and a scratch-off layer covering the printed content. The scratch-off layer may include a mass of a first solid ink and a mass of a second solid ink printed over the first solid ink in a distraction pattern. The toner image is formed of a toner that adheres to the substrate, while the scratch-off layer is made of a wax-based or other solid ink that may be removed from the substrate by scratching without removing the toner image. The distraction pattern includes varying pile heights that distract a viewer from any pile height variations that may exist in the toner image.

US Classification:

347 14, 347 19, 347 22

Abstract:

A method for detecting a defect in an inkjet print head for printing a substantially clear ink includes including an ultraviolet or infrared sensitive material in the substantially clear ink, marking a test image on a substrate by jetting the substantially clear ink through one or more jets of the inkjet print head to be evaluated, exposing the test image to activating radiation having a wavelength to which the included ultraviolet or infrared sensitive material responds. During or following the exposing, the test image is evaluated with an image sensor, and whether the inkjet print head or any one of the one or more jets thereof being evaluated is defective is then determined based on the evaluation. A system for the method is also set forth.

International Classification:

B41J 2/01

US Classification:

347102

Abstract:

An approach is provided for controlling ultraviolet-curable gel ink spread of a printed image. The approach involves causing, at least in part, one or more inks to be applied to a first substrate image area by one or more inkjets in a printing zone of a printer, the one or more inkjets being configured to form one or more first ink spots on the first substrate image area. The approach also involves determining a temperature of at least the first substrate image area in the printing zone. The approach further involves determining a first spot size of at least one of the one or more first ink spots. The approach additionally involves causing, at least in part, a temperature of at least a second substrate image area in the printing zone to be based, at least in part, on the determined first spot size.

B29C 64/236
B29C 64/241

Abstract:

An additive manufacturing system has a controller configured to modify numerical control programming instructions to form interlocking structures that improve object structural integrity in the Z-direction. The interlocking structures are produced by forming one layer with swaths that are separated by gaps and another layer that is formed over the gaps to fill the gaps and lay over the swaths forming the gaps.

Abstract:

An additive manufacturing system has a controller configured to operate an actuator to move a multi-nozzle extruder in an XY plane and rotate the multi-nozzle extruder about an axis perpendicular to the XY plane while operating the multi-nozzle extruder to form swaths in the XY plane. The controller operates the actuator and the multi-nozzle extruder to keep the nozzles of the extruder within perimeters formed for an object and to vary the speed and rotation of the extruder while extruding material to form precise structures.

Jason O'Neil - Rochester NY, US

International Classification:

B29C 64/209
B29C 64/118
B29C 64/321

Abstract:

An additive manufacturing system opens the valves in an extruder needed to form a swath and operates an actuator to move the extruder through a transition region with those valves open to establish an amount of extrusion material between a faceplate of the extruder and a portion of an object being formed that is adequate for formation of a swath. The length of the transition region is determined with reference to a viscosity of the material being extruded and a speed at which the extruder is moved to form the swath. The transition region can be perpendicular to a path of the extruder to form the swath or aligned with the path of the extruder to form the swath.

B29C 64/118
B29C 64/40

Abstract:

A method of operating a multi-nozzle extruder in an additive manufacturing system enables support structure to be formed while an object is also being formed. The method includes opening more than one nozzle in the multi-nozzle extruder, and operating an actuator with a controller to move the multi-nozzle extruder along a path to form a first group of multiple parallel ribbons of support structure simultaneously with material extruded from the more than one open nozzle.
