    摘要： A method for forming a stripper roller is described where, instead of a symmetrical, cylindrical paper-feed roller, an asymmetrical feed roller (or stripper roller) is used to separate a bottommost sheet from a stack of sheets. Eccentric portions of the feed roller are located at both ends of the roller, and the middle portion of the roller is cylindrical. In one embodiment, the eccentric end portions are formed by cutting ends of a cylindrical roller and then placing a shim between the center shaft and each end portion. Paper-feed springs oppose the eccentric portions of the feed roller, while a centrally located separator pad opposes the cylindrical middle portion of the feed roller. The extended radius at the apogee of the eccentric portions allows the eccentric portions to effectively reach out and grab the bottommost sheet even if the stack of sheets were only initially lightly contacting the roller. The eccentric portions of the feed roller also provide surges in the frictional force urging the bottommost sheets toward the separator pad. This surge in force acts to spread out (or pre-separate) the paper in the stack so the paper can be more easily separated by the separator pad.

    摘要： A facsimile machine containing an improved paper separator system is described where, instead of a symmetrical, cylindrical paper-feed roller, an asymmetrical feed roller (or stripper roller) is used to separate a bottommost sheet from a stack of sheets. Eccentric portions of the feed roller are located at both ends of the roller, and the middle portion of the roller is cylindrical. Paper-feed springs oppose the eccentric portions of the feed roller, while a centrally located separator pad opposes the cylindrical middle portion of the feed roller. The extended radius at the apogee of the eccentric portions allows the eccentric portions to effectively reach out and grab the bottommost sheet even if the stack of sheets were only initially lightly contacting the roller. The eccentric portions of the feed roller also provide surges in the frictional force urging the bottommost sheets toward the separator pad. This surge in force acts to spread out (or pre-separate) the paper in the stack so the paper can be more easily separated by the separator pad.

    摘要： In the preferred embodiment, an interlock switch is located on a first of two access doors of a printer. The second access door has an upwardly extending protuberance near its end. The switch is actuated for enabling the system by closing the second access door followed by closing the first access door. The protuberance on the second access door pushes upwardly on an arm of the switch as the first access door is closed, thus actuating the switch. This not only provides a reliable safety mechanism by insuring that the doors are properly closed, but eliminates the cost of a separate safety interlock switch for each access door.
