Image forming apparatus and method of detecting home position error |
摘要 |
An image forming apparatus and a method of detecting a home position error are provided. The image forming apparatus includes a plurality of developing units, a cam shaft, and a plurality of cams that are formed on the cam shaft to correspond to the respective developing units. A power transmitting element is installed between the plurality of developing units and the plurality of cams and selectively transmits a rotational force of a driving source to the plurality of developing units according to a rotational phase of the cam shaft. An indicating element is installed on the cam shaft and includes a plurality of indicating units. A sensor senses the plurality of indicating units. A home position error is detected each time when the indicating units pass through the sensor.
