A combination electro-optic sensor and switch including a printed wiring board supporting an electro-optic sensor enclosed in a sealed housing, a sleeve mounted on a shaft for rotation within the housing in the light path the electro-optic sensor with a portion of the shaft extending through the sealed housing and connected to a wire actuator, the engagement of the wire actuator by a copy sheet providing an approximately 20 millisecond response time of the sensor.

A printing system adapted for creating hard copy output from computer generated digital pulses. This system feeds blank or preprinted paper from a paper supply station through a xerographic processor wherein readable computer generated images are created thereon. The information bearing paper is then transported to a paper receiving station which comprises one or more paper receiving bins. Alternatively, an auxiliary feed path for the output paper is created to direct pages, under certain circumstances, to a sample print tray. Paper deflecting fingers are provided to divert pages to the sample print tray under the control of the operator in response to one of four conditions. These conditions include: (a) The feeding of a sample page through the processor when power is first applied to the machine after the machine has been in a powerless state, or (b) After a jam in the system has been cleared and it is desired to abort pages which have not been removed from the paper path. In this mode, the system may also cause the feeding of a sample page through the processor and direct it to the sample print tray, or (c) Any time during the normal operating cycle of the machine when a supplemental copy or a sample page is desired to be made to check the copy quality being produced by the system, or (d) When it is desired to print the contents of specified controller memory locations for diagnostic troubleshooting purposes.
