Patents by Inventor Randy R. SPRAGUE

Randy R. SPRAGUE has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20230221902
    Abstract: A processor of a printing apparatus obtains and maintains the media type of print media located in a media storage component of the printing apparatus. The processor also accesses a reference file containing different printing speed limits for different media types. The reference file can be maintained in an electronic storage component of the printing apparatus. The processor uses the reference file to determine an appropriate printing speed limit for a printing engine of the printing apparatus that corresponds to the media type of the print media in the media storage component. Further, a user interface of the printing apparatus can display an overspeed indicator, and/or the processor can stop the printing from occurring, based on a job-set printing speed of the printing engine being above the printing speed limit.

  • Patent number: 9156642
    Abstract: A system and method are provided for improving stack integrity for a set of image receiving media substrates at an output of a compiler in an image forming device by positioning a particularly configured substrate handling device downstream of the output of the compiler in a process direction. The substrate handling device is configured of a plurality of omni-directional wheeled devices that provide drive (traction) normal to a motor axis under control of one of a respective plurality of independent motors while allowing sliding in the motor axis direction. The omni-directional wheeled devices, in one embodiment, are configured with small roller wheels along the periphery of the wheel. When using three or more omni-directional wheeled devices, translational movement can be combined with rotation to deliver sheets of image receiving media exiting the compiler at a correct angle and lateral position for further processing.
