  • Method and apparatus for avoiding unnecessary computer peripheral calibration activities
    Patent number: 6915353
    Abstract: A method and apparatus for determining an appropriate recalibration duty cycle. The method instructs a network connected computer peripheral to access one or more servers to retrieve a timestamp. Retrieved timestamps are used to calculate the elapsed time since the last trigger-event (e.g., last calibration, printing activity, time of power-off, or the like). If the calculated elapsed time is less than a predetermined or dynamically determined threshold, the method instructs the peripheral to omit otherwise implemented calibration activities, e.g., a power surge reboot.

  • System for and method of toner flow control
    Patent number: 6760555
    Abstract: The present invention is directed to a sealing mechanism for use in a toner cartridge. The sealing mechanism includes a developer roller and a toner plow. The developer roller has an outer cylindrical surface. The toner plow includes a concave contact region configured to mate with the outer cylindrical surface of the developer roller and a toner plow face placed at an acute angle with respect to a longitudinal axis of the developer roller.
