Abstract:
1. A system for feeding and separating media in an image forming device, comprising: a pick mechanism having at least one rotatable pick roller for feeding a topmost media sheet from a stack of media sheets in a media storage location in a media process direction from an initial pick position into a media feed path; and at least one rotatable separator roller positioned opposite and spaced away from the at least one pick roller downstream from the initial pick position and forming an open nip with the at least one pick roller, the at least one separator roller being rotatable counter to the media process direction for separating an adjacent media sheet from the topmost media sheet and returning the adjacent media sheet to a point upstream from the at least one separator roller if the adjacent media sheet is double fed with the topmost media sheet when the topmost media sheet is fed from the initial pick position, the at least one separator roller being rotatably mounted below a media contact surface of an inclined media dam and having a portion of its surface radially extending through at least one aperture therein, wherein a tangential point of contact between the topmost media sheet and the at least one separator roller is downstream from and spaced vertically above a tangential point of contact between the topmost media sheet and the at least one pick roller, wherein a distance between a surface of the at least one pick roller and a surface of the at least one separator roller is about 10 mm.
