One of the significant service cost items in laser printers is the laser tube assembly. It is very difficult to fault isolate the laser from surrounding assemblies, namely the supporting electronics, modulator, raster output scanner optics, laser power supply and polygon assembly. If a detector is placed directly in conjunction with the laser tube, a specific fault code can identify the laser, power supply and harnessing as the area of failure, greatly reducing the steps in the fault isolation rocedure. Furthermore, if a laser
