摘要
An interpage gap control, which acts to optimize the throughput of a printer or other device, which utilizes fed pages, monitors the time for a page to be picked and fed to a sensor and the time for the page to pass the sensor. By using these time periods and other constants, the control calculates a delay time from the detection of the leading edge of the page at the sensor. This delay time must expire before the next page may be picked and fed. The control adjusts the delay period by comparing the time periods measured to reference values for the respective periods and if the measured values vary therefrom, adjusts the reference values. The adjustment of the values is made in small increments when the adjustment will tend to narrow the gap width and will replace the reference values with the measured value when the gap must be widened. This insures that the optimum width is approached cautiously, while expanding the gap quickly to avoid a jam condition when the measured time values indicate that the gap has unduly narrowed.
