I fix all brands of roll laminators for a living....
ultimate 65s have a adjustable potentiometer on the main board to set the temperature.....

sometimes customers load the machine adhesive side to the red rollers and people think the machine overheated.
telephone tech support is always free, feel free to give me a call
