Abstract:
An imaging station, comprising:a moving photoreceptor belt having sensing indicia, a belt sensor for detecting said sensing indicia and for producing a belt signal from that detection; a laser source for emitting a laser beam; a multifaceted rotating polygon for sweeping said laser beam across said moving photoreceptor so as to form a scan line in a scan line plane; a start-of-scan detector for sensing said sweeping laser beam and for producing start-of-scan signals when the laser beam is in position to begin writing a scan line; a motor for moving said photoreceptor belt at a speed that depends upon motor input power; a controller for receiving said belt signals and said start-of-scan signals, said controller for controlling said motor input power such that said belt signals are an integral multiple of said start-of-scan signals; and a roller over which said photoreceptor belt travels, wherein said roller has a perimeter that is a submultiple of a perimeter of said photoreceptor belt.
