Abstract
A fastener driver comprises a driver blade movable from a retracted position to a driven position and a lifter assembly for moving the driver blade from the driven position toward the retracted position. The fastener driver also includes a first sensor to detect the driver blade in the driven position, a latch which, in a locked position, maintains the lifter assembly in an engaged position, an actuator coupled to the latch for moving the latch between the locked position and a released position, in which the lifter assembly may move away from the driver blade, and a controller electrically connected with the first sensor and the actuator. In response to an absence of a signal from the first sensor after a predetermined time following initiation of a fastener driving operation, the controller triggers the actuator to move the latch from the locked position to the released position.
