    Abstract: A multiple sheet detecting system for use in a sheet feed path to provide a signal to a machine control when superposed sheets are fed past a detection station. The detection system has a source of illumination and photosensitive elements at the detection station. Illumination is interrupted by the presence of a sheet or sheets in the sheet path and also by a sample sheet such that a comparison is made between the sample and fed sheets. An electronic circuit coupled to the photosensitive elements which experience a change in resistance depending upon the transmittance of a sheet or sheets in the sheet path generates an output signal when there is a multiple sheet condition. The circuit may be calibrated for varying circuit parameters to accommodate different sheet weights and types.

    Abstract translation: 一种多张纸张检测系统，用于在纸张馈送路径中，当叠加的纸张被馈送通过检测站时，向机器控制提供信号。 检测系统在检测站具有照明源和感光元件。 照片由片材或片材在片材路径中的存在以及样品片材的中断，从而在样品和进给片材之间进行比较。 耦合到感光元件的电子电路，其在根据片材路径中的片材或片材的透射率而经历电阻变化时，当存在多张条件时，产生输出信号。 该电路可以针对不同的电路参数进行校准，以适应不同的纸张重量和类型。

    Abstract: A multiple-sheet-detecting system for use in a sheet feed path to provide signals to a machine control to indicate when superposed sheets are fed past a detection station. The detection system has a light source and photosensor located on opposite sides of the sheet path such that the illumination reaching the photosensor is interrupted by the presence of a sheet or sheets in the sheet path. An electronic circuit is coupled to the photosensor which experiences a change in resistance depending upon the transmittance of a sheet or sheets in the sheet path and provides an output signal when there is a multiple sheet condition. The electronic circuit includes a motor-driven potentiometer which is utilized as a memory for a previously fed sheet in a feedback circuit for comparison with a signal representative of the next sheet. The circuit may be calibrated for varying circuit parameters to accommodate different sheet weights and types.

    Abstract: A sheet stacking system is described herein which comprises an array of sheet stacking bins (11, 11a, 11b) for stacking a plurality of printed substrate sheets, a sheet feeding input path system for feeding selected sheets into a selected bin (11, 11a, 11b) to form a stack (51) therein, a bin fullness indicator system for indicating that the stack (51) has reached a preset allowable maximum, and a stacking control system (50), controlled by the bin fullness indicator system, to control the sheet feeding input path. The bin fullness indicator system includes a single stack height sensing system for measuring the stack height. A movable carriage system is employed for moving this single stack height sensing system from one bin to another to measure the stack height in respective ones of the bins (11, 11a, 11b). The stack height sensor includes a movable sensing element which is extended into an adjacent bin to detect the stack height therein. A signal generator is responsive to the sensing element position to provide control signals for the stacking control system.

    Abstract: A reproduction system which includes inter alia a user interface providing a means for programming a plurality of features associated with the execution of a copying job. The system includes a means for comparing the most recently selected feature with all previously programmed features in order to identify any mutually exclusive or undesirable feature pairs. Finally, the system also contains one or possibly multiple priority establishing methods or schemes for use in automatically resolving conflicting feature selections.
