    sound like fuser lamps are overheating.You probably need a PSU or BCU i would put my multimerter on the PSU wher the lamps plugg into if theres no 240 volts its the PSU if there is its the BCU.

    Good luck

    SC 680 could have something to do with the toner bottles, this is a memory chip error or bad conection between bottle and holder.

    hi

    It said the manual:
    SC-543
    Heating roller fusing lamp overheat
    The detected fusing temperature stays at 200 C or more for five seconds.

    Replecentment the PSU.

    And the SC-680 may be......
    Toner cartridge memory chip loose connection

    Memory chip problem

    Memory chip cable wiring problem
