    Check the thermostat. On some of the lovely models, they put multiple thermostats, in which 1 will arbitrarily pop-especially when you get the low temp errors.

    I 'try' to remember to run my machines a few degrees below the factory setting. It gives me a bit of a buffer of sorts, and helps with not popping so many thermostats. It may or may not help you, but it's just something I do and it works well. It is case-by-case of course.

    Thanks Cobiray. I'll check these items tomorrow and let you know how it pans out.

    Point taken Schooltech. I will look into making the adjustment.

    Thanks guys.

    Have a good night.

    Try a new fusing unit too. They are user replaceable on these things anyway. I think I've had to replace an IH unit before too, can't remember if it was 544 tho.

    And all I ask is a tall ship and a star to steer her by.

    Two things:
    1) based on your description, I would be quite suspicious of the quality and quantity of the voltage being supplied to the machine by the outlet it is plugged into,
    2) You will have access to knowledge from far more Ricoh experienced people if you start a new thread rather than comment on an old thread that's been dead for years.
    Good luck!
