ABSTRACT:
An apparatus for feeding porous sheets of media from a stack of such sheets includes a support structure for supporting the stack. A gas conduit is mounted on the support structure and has an outlet that is oriented so that, when the stack is positioned on the support structure, the outlet is directed towards a first sheet of the stack. The gas conduit is in fluid communication with a gas supply so that a stream of gas can be directed onto the first sheet to penetrate the first sheet and generate a cushion of gas between the first sheet and a second sheet to separate the first and second sheets. A sheet feed mechanism feeds the first sheet from the stack once the first and second sheets are separated.
