    220 Laser synchronization detection error B246
    The 1st laser synchronization detection unit could not detect the line synchronization signal (DETP0) within 500 ms while the polygon mirror motor was operating at normal speed. Note: The unit polls for the signal every 50 ms. This SC is issued after the 10th attempt fails to detect the signal.

    • Laser synchronization boardconnector loose, broken, defective
    • Laser synchronization detection board is not installed correctly (out of alignment)
    • Laser synchronization board defective
    • IPU defective

    Also could be the poly mirror, laser emitter or door switches.

    Computers are serious tools, Michael!
