Abstract

A sheet feeding apparatus in which a trailing vacuum plenum moves in unison with a guide. The guide engages an edge of the stack to align the sheets thereof. The trailing edge vacuum plenum is positioned over the stack to acquire a trailing portion of the sheet. The sheet feeding apparatus includes a leading vacuum plenum positioned over the stack to acquire a leading portion of the sheet. A sheet transport advances the sheet acquired by the leading vacuum plenum from the stack.
