Separation of individual sheets of paper from a paper stack in a paper feeder is difficult due to the inability to break contact between the sheet to be fed and the adjacent sheets. The contact forces/mechanisms involved can be the result of physical surface condition of the paper (surface roughness, moisture content, static, etc.), cut edges of the paper being ragged or multicut sheets that have intermixed fibers at the edges and the weight of the stack for a bottom feeder.
