A method of operation of a workpiece displacement system includes: providing a head including a conduit, a recess port, and a channel, the conduit configured such that its major axis intersects the recess port and the channel; inserting a force distribution member into the recess port; and supplying a negative pressure state through the head and the force distribution member. The method comprises hot-rolling a slab comprising 0. The handle is pivotally attached to the housing and has a pair of actuating arms that are engageable with the actuator. The cooling apparatus is adapted to move cooling air capable of cooling the fuser assembly.
