More Information
Summary:An image forming apparatus may include an engine portion used to perform an image forming job, a step motor configured to start the engine portion, a driver including a resistor that measures current that flows to a coil of the step motor and is configured to provide a predetermined constant current to the step motor, and a drive controller configured to measure a load level of the step motor based on a voltage value of the resistor and to control the driver to provide the constant current that corresponds to the measured load level.
