Abstract

An imaging apparatus includes a sheet picking mechanism drive unit that includes a sheet pick gear train for driving a sheet picking mechanism to transport a sheet from a stack of print media along the sheet feed path. A print media dam is pivotably coupled at an axis to the imaging apparatus. The print media dam has at least one dam member and a first gear. Each dam member has a media engaging surface. A drive mechanism is drivably coupled between the sheet picking drive mechanism and the first gear to move the dam member between an extended position and a retracted position. When the dam member is in the extended position, the media engaging surface is positioned to interrupt the sheet feed path. When the dam member is in the retracted position, the media engaging surface is positioned to not interrupt the sheet feed path.
