Patent number: 11912045Abstract: A method of operating a printer evaluates the effect of printing a print job with two different orientations of the image content data for the print job. The orientation that produces the least increase in the cross-process direction displacement error for the inkjets in the printer is selected for printing the print job. By attenuating the increase in cross-process direction displacement error, the interval between printhead maintenance operations is increased.Type: GrantFiled: March 24, 2022Date of Patent: February 27, 2024Assignee: Xerox CorporationInventors: Jason M.

Patent number: 11917337Abstract: The present specification relates to image capture. More specifically, it relates to selective image capture for sensor carrying devices or floats deployed, for example, on the open sea. In one form, data is generated on the sensor carrying devices or floats by an on-board Inertial Measurement Unit (IMU) and is used to automatically predict the wave motion of the sea. These predictions are then used to determine an acceptable set of motion parameters that are used to trigger the on-board camera(s). The camera(s) then capture images. One consideration is that images captured at or near the peak of a wave crest with minimal pitch and roll will contain fewer obstructions (such as other waves). Such images provide a view further into the horizon to, for example, monitor maritime sea traffic and other phenomenon. Therefore, the likelihood of capturing interesting objects such as ships, boats, garbage, birds, . . . etc. is increased.Type: GrantFiled: August 31, 2021Date of Patent: February 27, 2024Assignee: XEROX CORPORATIONInventors: Matthew A. Shreve, Eric Cocker

Patent number: 11917289Abstract: A system is provided which obtains images of a physical object captured by an AR recording device in a 3D scene. The system measures a level of diversity of the obtained images, for a respective image, based on at least: a distance and angle; a lighting condition; and a percentage of occlusion. The system generates, based on the level of diversity, a first visualization of additional images to be captured by projecting, on a display of the recording device, first instructions for capturing the additional images using the AR recording device. The system trains a model based on the collected data. The system performs an error analysis on the collected data to estimate an error rate for each image of the collected data. The system generates, based on the error analysis, a second visualization of further images to be captured. The model is further trained based on the collected data.Type: GrantFiled: June 14, 2022Date of Patent: February 27, 2024Assignee: Xerox CorporationInventors: Matthew A. Shreve, Robert R. Price

Patent number: 11912013Abstract: Ink-based digital printing systems useful for ink printing include a rotatable charge-retentive reimageable surface layer configured to receive a layer of fountain solution. The fountain solution is carried to the charge retentive surface by a fog or mist including fountain solution aerosol particles, dispersed gas particles, and charge directors that impart charge to the fountain solution aerosol particles. The charge-retentive reimageable surface may be charged to a uniform potential, and selectively discharged using an ROS according to image data to form an electrostatic latent image. The charged fountain solution adheres to portions of the charge-retentive reimageable surface according to the electrostatic latent image to form a fountain solution image thereon. The fountain solution image can be partially transferred to an imaging blanket, where the fountain solution image is inked. The resulting ink image may be transferred to a print substrate.Type: GrantFiled: January 19, 2021Date of Patent: February 27, 2024Assignee: Xerox CorporationInventors: Kathryn F.

Publication number: 20240061630Abstract: The present disclosure discloses methods and systems for managing multiple priority jobs at a multi-function device. The method includes receiving a first job at the multi-function device, wherein the first job is to be completed within a pre-defined time. Then, a second job is received at the multi-function device. Upon receiving the second job, a pre-defined algorithm is run to determine an execution order for the first job and the second job. Based on the pre-defined algorithm, either continue executing the first job or start executing the second job.

Patent number: 11906915Abstract: Printing apparatuses include a photoreceptor adapted to print an image by applying marking material to print media, a fuser adapted to heat the marking material on the print media, and a controller. The controller determines the amount of marking material per unit area of the image before the fuser heats the marking material on the print media. The controller rasterizes the image to produce a bitmap of the image, but the amount of marking material per unit area for the image is determined before completion of rasterization and marking of the image. The controller also adjusts the operating temperature of the fuser to a fusing temperature based on the amount of marking material per unit area of the image, causes the photoreceptor to print the image on the print media using the bitmap of the image, and causes the fuser to fuse the marking material to the print media.Type: GrantFiled: April 28, 2021Date of Patent: February 20, 2024Assignee: Xerox CorporationInventors: Michael J.
