Soft close print paper drawer

A door closing mechanism, comprising

• a fixed chassis defining a chassis plane;
• a lever arm joined to the fixed chassis and pivotable at a proximal portion about a lever arm pivot axis from a first lever arm limit state to a second lever arm limit state, the lever arm comprising a first bearing surface at a first lever arm distance and a second bearing surface at a second lever arm distance, the first bearing surface being disposed a bearing surface distance from the second bearing surface;
• an energy storage element operably integrated with the lever arm;
• a cam plate being translatable toward the lever arm from a first cam position to a second cam position and pivotable about a cam plate pivot axis from a first cam limit state to a second cam limit state, the cam plate comprising a first cam surface and a second cam surface, the first cam surface being oriented at a positive angle relative to the chassis plane and aligned generally co-planar with the first bearing surface, the second cam surface being oriented at a negative angle relative to the chassis plane and aligned generally co-planar with the second bearing surface;
• and
• wherein the bearing surface distance is substantially equal to a cam surface distance separating a distal end of the first cam surface and a proximal end of the second cam surface.

A door closing apparatus for a document processing device, comprising

• a document processing device chassis defining a chassis plane;
• a drawer translatably mounted on the document processing device chassis at the chassis plane and translatable from a first open state to a second intermediate state and to a third closed state;
• a lever arm joined to the document processing device chassis and pivotable at a proximal portion about a lever arm pivot axis from a first lever arm limit state to a second lever arm limit state, the lever arm comprising a first bearing surface extending outwardly from the lever arm at a first lever arm distance and a second bearing surface extending outwardly from the lever arm at a second lever arm distance, the first bearing surface being disposed a bearing surface distance from the second bearing surface;
• an energy storage element operably integrated with the lever arm;
• a cam plate joined to the drawer and pivotable about a cam plate pivot axis from a first cam limit state to a second cam limit state, the cam plate comprising a first cam surface extending outwardly from the cam plate and a second cam surface extending outwardly from the cam plate, the first cam surface being oriented at a positive angle relative to the chassis plane and aligned generally co-planar with the first bearing surface, the second cam surface being oriented at a negative angle relative to the chassis plane and aligned generally co-planar with the second bearing surface;
• and
• wherein upon translating the drawer under a first force from the first open state to the second intermediate state the first cam surface engages the first bearing surface to cause the lever arm to pivot about the lever arm pivot axis and store energy in the energy storage element;
• and
• upon translating the drawer under the first force from the second intermediate state the first bearing surface disengages the first cam surface and the second bearing surface engages the second cam surface and exerts a second force released from the energy storage element to urge the drawer to the third closed state.
