Claim Text:
1. A media feed system in an image forming device, comprising: a frame; a media support for holding a media stack having one or more media sheets, the media support abutting the frame; a shaft rotatably mounted to the frame and positioned above the media stack, the shaft operably coupleable to a drive source in the image forming device; a pick roll coupled to the shaft and rotatable therewith to pick a sheet of media from the media stack and feed the picked media sheet into a media feed path in a media feed direction, the pick roll including: and, an aligner for aligning a leading edge of the picked media sheet to be transverse to the media feed direction, the aligner disposed downstream of the pick position at a distance that is less than a sum of the first and second circumferential lengths and greater than the first circumferential length, the aligner positioned transverse to the media feed path, wherein, when the pick tire initially contacts the media sheet at the pick position with the wide tread portion, the wide tread portion applies the first media feeding force to the media sheet to move the sheet in the media feed direction and into the media feed path, and, as the pick tire is further rotated the narrow tread portion contacts the picked media sheet to apply the second media feeding force allowing the leading edge of the media sheet to contact and align with the aligner.
