Abstract
Separation strips in a dam aid in the separation of adjacent sheets of media being fed from a stack of sheets so that only one sheet is fed to a process station and, more particularly, to separating the uppermost or top sheet of a stack of sheets from the next adjacent sheet during feeding of the top sheet from the stack of sheets of media. When a lift plate is present that adjusts the height of the media stack, rotation of the separation strips to maintain a constant separation angle improves media feed reliability. Curvature of the separation strips may also maintain the separation angle as the lift plate raises the position of the top media sheet.
