Claim:
1. A media path assembly in an imaging device, comprising: a media guide positioned adjacent and transverse to a media path between a first nip and a second nip of the imaging device, the media guide directing a leading edge of a media sheet exiting the first nip into the second nip in a media process direction, the media guide having a curved surface forming a bubble chamber across the media path; and, a first flag assembly and a second flag assembly positioned adjacent to the media guide and the bubble chamber, the first and second flag assemblies positioned transverse to the media path and aligned with each other, a position of the second flag assembly corresponding to a location in the media guide at which a media sheet of a first media size contacts the second flag assembly when the media sheet of the first media size passes through the media path and at which the second flag assembly is not contacted by a media sheet of a second media size that is less than the first media size when the media sheet of the second media size passes through the media path, a position of the first flag assembly corresponding to a location in the media guide at which the media sheet of the first media size and the media sheet of the second media size contact the first flag assembly when passing through the media path, wherein the first flag assembly comprises a bubble sensor that is operative to indicate formation in the bubble chamber of a bubble in the media sheet exiting the first nip and, when the media sheet exiting the first nip is of the first media size, the second flag assembly applies a balancing force thereto relative to a force applied by the first flag assembly to the media sheet exiting the first nip so that the leading edge thereof when entering the second nip is substantially aligned with the second nip.
