An apparatus and method are provided for adjusting the amount of light emitted by registration sensors. The apparatus comprises a first registration sensor emitting and receiving light for detecting a developed first registration pattern, a second registration sensor emitting and receiving light for detecting a developed second registration pattern, a signal converter converting a first received light signal received by the first registration sensor and a second received light signal received by the second registration sensor, a light controller outputting a first control signal in response to the converted first received light signal for adjusting an amount of a first emitted light by the first registration sensor, or a second control signal in response to the converted second received light signal for adjusting an amount of a second emitted light by the second registration sensor, a first registration sensor operator operating the first registration sensor in response to the first control signal, and a second registration sensor operator operating the second registration sensor in response to the second control signal.
