    [Misc] Warming Up RISO HC5500 .. Please Advice

    I just got this message on the lcd screen when i turn on the machine
    "waming Up" but it gets stuck on that message for like 10 minutes then i got a error message
    machine has been reset as factory default, but still with the same error.
    any advice?

    thanks in advance
