  • Patent number: 8068252
    Abstract: This disclosure provides a printing method and system including two or more integrated image marking engines, wherein the printing system is operated with less than the total number of image marking engines to generate the maximum specified prints per minute associated with the printing system. According to one exemplary embodiment, each image marking engine is controlled to be inactive in a round-robin manner to maintain substantially equal running time on each image marking engine or a substantially equal number of printed sheets on each marking engine.

  • Patent number: 7853182
    Abstract: A printing fluid dispenser system for multi-printer engine assembly is disclosed. The system includes a first dispenser that is adjacent to the print engine that is configured to pass printing fluid to an associated printing engine, a second dispenser adjacent to the first dispenser that is configured to store the printing fluid and pass the printing fluid to the first dispenser as the first dispenser passes the printing fluid to the printing engine and a sensor configured to detect when the printing fluid remaining in one of the first or second dispensers drops below a predetermined threshold.
