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.
