Beschreibung
Zusammenfassung:	A print drum for carrying sheets of media during printing, including a rotatable carrier drum generally defining an outer cylindrical boundary about a drum axis, and at least one media control member extending laterally substantially parallel to the carrier drum axis. The media control member is controllably movable between (1) a first position extending beyond the carrier drum boundary to define a lateral alignment barrier for a leading edge of a media sheet when adding the media sheet to the carrier drum, (2) a second position beneath the outer cylindrical boundary when printing on the added media sheet, and (3) a third position projecting outwardly of the outer cylindrical boundary to push the leading edge of the added sheet of media away from the outer cylindrical boundary.
