An Unload Stacker Sensor Which Will Prevent The Stacker From Being Unloaded if Blocked by a Person or Object

Currently, the stacker on many high volume printer products will unload whether or not the area in front of the stacker is clear. Therefore, there's a potential for someone standing in front of the finisher to be hit when the stacker is unloaded. Or, if an item is temporarily placed in front of the finisher, and the stacker is unloaded, the item and/or stacker could be damaged.

A new stacker sensor would detect whether or not the area in front of the stacker door is clear before attempting to unload the stacker. If the area in front of the stacker is blocked, the stacker will not unload until it senses the area is clear. If the stacker does start unloading and then comes into contact with a person or object, the stacker will halt (much like what an automatic garage door opener does) until the area in front of the stacker is clear.
