Classification: CPC B  G | IPC B  G

Claim 8:
9. A method for controlling an image forming apparatus, the method comprising:
sensing an amount of current of a power supplied to a motor to drive a fuser for a predetermined time by using a sensor;
analyzing a frequency component for the current supplied to the motor by using the sensed amount of current in a case in which a warm-up of the fuser is required; and
determining an occurrence of a jam in the fuser based on the analyzed frequency component based on a predetermined frequency band in the analyzed frequency component corresponding to pre-stored information relating to the predetermined frequency band during a paper jam, wherein the occurrence of a jam is determined based on the magnitude of the predetermined frequency band in the analyzed frequency component and pre-stored information relating to the frequency component during normal operation, wherein the processor, based on the jam occurring, suspends an operation currently in progress.
