PURPOSE:To prevent a printing paper from burning by controlling the feeding of paper and heat emitting of a fixing part responding to paper end tip detecting signal and stacked paper detecting signal. CONSTITUTION:The stacker 6, which stacks the printing paper 2 fed from a paper feeding roller 4, and the paper end tip detector, which detects the end tip of the printing paper 2, and a stacked paper detector, which detects whether or not the printing paper 2 exists in the stacker 6 are provided and a heating roller 7 is provided in the fixing part 5. If the printing paper 2 is wound up to the heating roller 7 while a paper feeding motor is being driven for T seconds, the stacked paper signal is turned off, a paper jamming alarm signal and a heater cutting off signal are turned on to cut off a heating power source. Thus the printing paper is prevented from burning. |
