A cover of a stencil printer is hingedly mounted to a frame, and movable between a closed and open positions. The cover includes an elongate opening formed therein and a movable door configured to selectively close the elongate opening. The elongate opening is sized to enable the stencil and/or a tooling tray to pass through. A controller is configured to control movement of the movable door between a closed position and an open position. A sensor assembly is proximate the elongate opening. The sensor assembly is coupled to the controller and configured to detect an object within the elongate opening when moving the movable door to the closed position. The sensor is configured to generate a signal to the controller when detecting an object within the elongate opening. The controller, upon receiving the signal from the sensor, is configured to move the movable door to the open position.
