Abstract: An image forming apparatus and a method for controlling the operation of the image forming apparatus are provided to prevent the unnecessary driving of an LSU(Laser Scanning Unit) motor by driving the LSU motor according to the temperature around the LSU motor. A memory(330) stores temperature around an LSU motor of a print engine part and an LSU time value. A temperature sensor(340) measures the temperature around the LSU motor. A warming up counter(350) receives information about one of a power-on state and a print command, and measures the driving time of the LSU motor. A print controller(310) compares the LSU time value according to the temperature around the LSU motor with the driving time of the LSU motor, and then determines whether the driving of the LSU motor is ended.

Abstract: Disclosed is a method for controlling the temperature of a heat roller and an image forming apparatus based on the same. The image forming apparatus of the present invention includes: a heat roller for heating a printing paper having a toner image formed thereon to completely fuse the toner image to the printing paper; a heat lamp for heating the heat roller; and a controller for controlling the driving of the heat lamp, whereby the heat roller is maintained at a designated target temperature level during a pre-printing period. As such, it becomes possible to prevent a problem with the fusing process caused by low temperature of the heat roller during the pre-printing period for subsequent printing.

Abstract: Disclosed are a method of preventing overheating of a fuser assembly (100) and an apparatus using the same. The method of preventing overheating of a fuser assembly includes inspecting whether a temperature of a fuser assembly (100) is higher than a predetermined temperature. If the temperature of the fuser assembly (100) is higher than the predetermined temperature it is determined whether there is a print command. A print sheet is passed through the fuser assembly, and conveyed to a predetermined location. The temperature is again inspected if there is no print command. If the temperature is lower than the predetermined temperature it is determined whether a predetermined time has lapsed. The temperature is again inspected if the predetermined time did not lapse.
