摘要：
An imaging apparatus includes a machine frame, a printhead housing containing a printhead for generating a laser beam, and a position sensing device. The position sensing device includes a position sensing device frame and a position sensor for sensing a position of the laser beam. The position sensing device frame is interposed between the machine frame and the printhead housing. Each of the machine frame, the printhead housing and the position sensing device frame include at least one reference feature that in combination accurately reference the position of the printhead housing to the machine frame.
